| 1 | Intercalated phases of transition metal dichalcogenides显示文摘Two‐dimensional transition metal dichalcogenides(TMDs)play host to a wide range of novel topological states,such as quantum spin Hall insulators,superconductors,and Weyl semimetals.The rich polymorphism in TMDs suggests that phase engineering can be used to switch between different charge order states.Intercalation of atoms or molecules into the van der Waals gap of TMDs has emerged as a powerful approach to modify the properties of the material,leading to phase transition or the formation of substoichiometric phases via compositional tuning,thus broadening the electronic and optical landscape of these materials for a wide range of applications.Here,we review the current efforts in the preparation of intercalated TMD.The challenges and opportunities for intercalated TMDs to create a new device paradigm for material science are discussed. | Ziying Wang Runlai Li Chenliang Su Kian Ping Loh | 2020 | SmartMat2020，1，1： | 2 |
| 2 | Green and scalable electrochemical routes for cost‐effective mass production of MXenes for supercapacitor electrodes显示文摘One of the most unique properties of two-dimensional carbides and nitrides of transition metals(MXenes)is their excellent water dispersibility and yet possessing superior electrical conductivity but their industrial-scale application is limited by their costly chemical synthesis methods.In this work,the niche feature of MXenes was capitalized in the packed-bed electrochemical reactor to produce MXenes at an unprecedented reaction rate and yield with minimal chemical waste.A simple NH4F solution was employed as the green electrolyte,which could be used repeatedly without any loss in its efficacy.Surprisingly,both fluoride and ammonium were found to play critical roles in the electrochemical etching,functionalization,and expansion of the layered parent materials(MAXs)through which the liberation of ammonia gas was observed.The electrochemically produced MXenes with excellent conductivity,applied as supercapacitor electrodes,could deliver an ultrahigh volumetric capacity(1408 F cm^(−3))and a volumetric energy density(75.8 Wh L^(−1)).This revolutionary green,energy-efficient,and scalable electrochemical route will not only pave the way for industrial-scale production of MXenes but also open up a myriad of versatile electrochemical modifications for improved functional MXenes. | Zimo Huang Jiadong Qin Yuxuan Zhu Kelin He Hao Chen Hui Ying Hoh Munkhbayar Batmunkh Tania MBenedetti Qitao Zhang Chenliang Su Shanqing Zhang Yu Lin Zhong | 2023 | Carbon Energy2023，5，10： | 1 |
| 3 | Adaptive Consensus Quantized Control for a Class of High-Order Nonlinear Multi-Agent Systems With Input Hysteresis and Full State Constraints显示文摘For a class of high-order nonlinear multi-agent systems with input hysteresis,an adaptive consensus output-feedback quantized control scheme with full state constraints is investigated.The major properties of the proposed control scheme are:1)According to the different hysteresis input characteristics of each agent in the multi-agent system,a hysteresis quantization inverse compensator is designed to eliminate the influence of hysteresis characteristics on the system while ensuring that the quantized signal maintains the desired value.2)A barrier Lyapunov function is introduced for the first time in the hysteretic multi-agent system.By constructing state constraint control strategy for the hysteretic multi-agent system,it ensures that all the states of the system are always maintained within a predetermined range.3)The designed adaptive consensus output-feedback quantization control scheme allows the hysteretic system to have unknown parameters and unknown disturbance,and ensures that the input signal transmitted between agents is the quantization value,and the introduced quantizer is implemented under the condition that only its sector bound property is required.The stability analysis has proved that all signals of the closed-loop are semi-globally uniformly bounded.The Star Sim hardware-in-the-loop simulation certificates the effectiveness of the proposed adaptive quantized control scheme. | Guoqiang Zhu Haoqi Li Xiuyu Zhang Chenliang Wang Chun-Yi Su Jiangping Hu | 2022 | IEEE/CAA Journal of Automatica Sinica2022，9，9： | 1 |
| 4 | Plasma tailoring in WTe_(2)nanosheets for efficiently boosting hydrogen evolution reaction显示文摘2D transition metal dichalcogenides(TMDs)have been considered as promising non-precious electrocatalysts for the hydrogen evolution reaction(HER).However,their limited active sites and poor electric conductivity pose a significant hurdle to their HER performance,resulting in a large overpotential.Here,we report the defect engineering in ultrathin tungsten telluride(WTe_(2))nanosheets with semimetal nature to improve hydrogen evolution effectively.We find that the oxygen plasma etching imposes a cutting effect on WTe_(2)nanosheets,resulting in a large number of tungsten vacancies.Particularly,the sample after plasma treatment for 10 min shows a feather-like structure with an overpotential of 251m V at 10 m A/cm~2and a Tafel slope of 94 m V/dec,which is 4 times lower than the Tafel slope of pristine nanosheets.Further first-principles calculations shed light on the evolution of defect-rich WTe_(2)nanosheets and offer rational explanation to their superiority in efficient hydrogen evolution. | Xin Wang Jun Wang Bin Wei Nan Zhang Junyuan Xu Hongwei Miao Lifeng Liu Chenliang Su Ying Li Zhongchang Wang | 2021 | Journal of Materials Science & Technology2021，，19： | 1 |
| 5 | Promoting near-infrared photocatalytic activity of carbon-doped carbon nitride via solid alkali activation显示文摘Ultrabroad spectral absorption is required for semiconductor photocatalysts utilized for solar-to-chemical energy conversion.The light response range can be extended by element doping,but the photocatalytic performance is generally not enhanced correspondingly.Here we present a solid alkali activation strategy to synthesize near-infrared(NIR)light-activated carbon-doped polymeric carbon nitride(A-cPCN)by combining the copolymerization of melamine and 1,3,5-trimesic acid.The prepared A-cPCN is highly crystalline with a narrowed bandgap and enhanced efficiency in the separation of photogenerated electrons and holes.Under irradiation with NIR light(780 nm≥λ≥700 nm),A-cPCN shows an excellent photocatalytic activity for H_(2)generation from water with rate of 165µmol g^(−1)h^(−1),and the photo-redox activity for H_(2)O_(2)production(109µmol g^(−1)h^(−1))from H_(2)O and O_(2),whereas no observed photocatalytic activity over pure PCN.The NIR photocatalytic activity is due to carbon doping,which leads to the formation of an interband level,and the alkali activation that achieved shrinking the transfer distance of photocarriers.The current synergistic strategy may open insights to fabricate other carbon-nitrogen-based photocatalysts for enhanced solar energy capture and conversion. | Qingfeng Li Can Ren Chuntian Qiu Tingchao He Qitao Zhang Xiang Ling Yangsen Xu Chenliang Su | 2021 | Chinese Chemical Letters2021，32，11： | 1 |

| 10 | Engineering biocompatible TeSex nano-alloys as a versatile theranostic nanoplatform显示文摘Photothermal nanotheranostics, especially in the near infrared II(NIR-II) region, exhibits a great potential in precision and personalized medicine, owing to high tissue penetration of NIR-II light.NIR-II-photothermal nanoplatforms with high biocompatibility as well as high photothermal effect are urgently needed but rarely reported so far. Te nanomaterials possess high absorbance to NIR-II light but also exhibit high cytotoxicity, impeding their biomedical applications. In this work, the controllable incorporation of biocompatible Se into the lattice of Te nanostructures is proposed to intrinsically tune their inherent cytotoxicity and enhance their biocompatibility, developing TeSe_(x) nano-alloys as a new kind of theranostic nanoplatform. We have uncovered that the cytotoxicity of Te nanomaterials primarily derives from irreversible oxidation stress and intracellular imbalance of organization and energy, and can be eliminated by incorporating a moderate proportion of Se(x = 0.43). We have also discovered that the as-prepared TeSe_(x) nano-alloys have extraordinarily high NIR-II-photothermal conversion efficiency(77.2%),^(64)Cu coordination and computed tomography contrast capabilities, enabling high-efficacy multimodal photothermal/photoacoustic/positron emission tomography/computed tomography imaging-guided NIR-II-photothermal therapy of cancer. The proposed nano-alloying strategy provides a new route to improve the biocompatibility of biomedical nanoplatforms and endow them with versatile theranostic functions. | Xiang Ling Zhaokui Jin Qi Jiang Xiaotao Wang Bin Wei Zhongchang Wang Yangsen Xu Tianye Cao Jonathan W.Engle Weibo Cai Chenliang Su Qianjun He | 2021 | National Science Review2021，8，6： | 0 |
| 11 | Engineering the Local Coordination Environment of Single-Atom Catalysts and Their Applications in Photocatalytic Water Splitting:A Review显示文摘Single-atom catalysts(SACs),with atomically dispersed metal atoms anchored on a typical support,representing the utmost utilization effi ciency of the atoms,have recently emerged as promising catalysts for a variety of catalytic applications.The electronic properties of the active center of SACs are highly dependent on the local environment constituted by the single metal atom and its surrounding coordination elements.Therefore,engineering the coordination environment near single metal sites,from the fi rst coordination shell to the second shell or higher,would be a rational way to design effi cient SACs with optimized electronic structure for catalytic applications.The wide range of coordination confi gurations,guaranteed by the multiple choices of the type and heterogeneity of the coordination element(N,O,P,S,etc.),further off er a large opportunity to rationally design SACs for satisfactory activities and investigate the structure-performance relationship.In this review,the coordination engineering of SACs by varying the type of coordination element was elaborated and the photocatalytic water splitting of SACs was highlighted.Finally,challenging issues related to the coordination engineering of SACs and their photocatalytic applications were discussed to call for more eff orts devoted to the further development of single-atom catalysis. | Hongli Sun Yunfei Ma Qitao Zhang Chenliang Su | 2021 | Transactions of Tianjin University2021，27，4： | 0 |
| 12 | Chiral self-assembly of terminal alkyne and selenium clusters organic–inorganic hybrid显示文摘The on-surface self-assembly of inorganic atomic clusters and organic molecules offers significant opportunities to design novel hybrid materials with tailored functionalities.By adopting the advantages from both inorganic and organic components,the hybrid self-assembly molecules have shown great potential in future optoelectrical devices.Herein,we report the co-deposition of 4,8-diethynylbenzo[1,2-d-4,5-d0]bisoxazole(DEBBA)and Se atoms to produce a motif-adjustable organic–inorganic hybrid self-assembly system via the non-covalent interactions.By controlling the coverage of Se atoms,various chiral molecular networks containing Se,Se_(6),Se_(8),and terminal alkynes evolved on the Ag(111)surface.In particular,with the highest coverage of Se atoms,phase segregation into alternating one-dimensional chains of non-covalently bonded Se_(8) clusters and organic ligands has been noticed.The atom-coverage dependent evolution of self-assembly structures reflects the remarkable structural adaptability of Se clusters as building blocks based on the spontaneous resize to reach the maximum non-covalent interactions.This work has significantly extended the possibilities of flexible control in self-assembly nanostructures to enable more potential functions for broad applications. | Zhi Chen Tao Lin Haohan Li Mingzi Sun Chenliang Su Bolong Huang Kian Ping Loh | 2022 | Nano Research2022，15，3： | 0 |
| 13 | Recent advances in nature-inspired nanocatalytic reduction of organic molecules with water显示文摘Nature has provided us the assurance and inspiration for thousands of years in synthesizing value-added chemicals,with the assistance of reactive hydrogen species,and water as the ultimate hydrogen source.However,the natural photosynthesis is inefficient due to some intrinsic properties,urging people not only to learn from but also surpass during nature imitation.In this review,we summarized recent progresses on reactive hydrogen species-assisted nanocatalytic reduction of organic molecules towards value-added fine chemicals and pharmaceuticals,with water as the hydrogen source,and especially highlighted how photocatalytically or electrocatalytically evolved reactive hydrogen species synergize with biocatalytic centers and nanocatalytic sites for reduction of organic molecules.The design principles of collaborative semi-artificial systems and nanocatalytic artificial systems,the structure tuning of catalysts for the evolution and utilization of hydrogen species,and the determination of reactive hydrogen species for mechanistic insights were discussed in detail.Finally,perspectives were provided for further advancing this emerging area of nanocatalytic reduction of organic molecules from water(or proton)and organics. | Hongli Sun Wei Ou Like Sun Bo Wang Chenliang Su | 2022 | Nano Research2022，15，12： | 0 |
| 14 | Structure engineering of PtCu_(3)/C catalyst from disordered to ordered intermetallic compound with heat-treatment for the methanol electrooxidation reaction显示文摘Platinum based alloys are hereinto the mostly used methanol oxidation catalysts.However,there are limited ways to improve the methanol oxidation reaction(MOR)performance of catalysts in terms of both activity and stability.Herein we developed a simple heat-treatment method to synthesize PtCu_(3)/C intermetallic compound catalyst with lattice compression.The as-prepared PtCu_(3)/C-1000 exhibited high specific activity of 3.23 mA·cm^(-1) and mass activity of 1,200 mA·mgPt^(-1),which is much higher than the PtCu_(3)/C-untreated and commercial Pt/C catalysts,respectively.The XAS and DFT results shows the high activity of the catalyst towards MOR comes from the tightening of the Pt-M bond,which leads to the decrease of Fermi energy level and the make it difficulty in adsorbing carbon intermediates,thus releasing more active sites to promote the improvement of MOR performance.Moreover,the PtCu_(3)/C-1000 shows better stability which is due to the surface-rich Pt prevents Cu from dissolution. | Zihao Xing Jun Li Shun Wang Chenliang Su Huile Jin | 2022 | Nano Research2022，15，5： | 0 |
