| 3 | Study on Property of Polypropylene Catalyst with New Internal Donor显示文摘A P-substituted sulfonyl-containing compound was synthesized in the lab. The structure of the compound was demonstrated by 1H and 31P NMR. The propylene polymerization catalysts were prepared by incorporating an internal donor, and the content of Ti, H and C in the catalysts was also checked by elemental analysis. The effect of dosage of the donor, the Al/Ti ratio and the polymerization temperature on the catalyst activity were studied, the results suggested that the dosage of donor, the Al/Ti ratio and the polymerization temperature could affect not only the activity of catalyst but also the isotacticity index of the polymer. A catalyst with high activity was selected, and the polypropylene formed in the presence of this catalyst had high isotacticity index. | Yin Baozuo Wang Liang Yi Jianjun Cui Chunming | 2011 | China Petroleum Processing & Petrochemical Technology2011，13，4： | 1 |

| 10 | Rare-earth metal catalysts for alkene hydrosilylation显示文摘Rare-earth metal catalyzed hydrosilylation of alkenes has emerged as a powerful and selective strategy for the synthesis of organosilanes. This transformation can offer distinctive catalytic sequences and reaction patterns from other catalysts because of the high electropositivity and lack of oxidative-addition process of rare-earth metal. This review summarizes the rare-earth metal catalysts for hydrosilylation of alkene according to the type of ligands. The synthesis and structure of rare-earth metal catalysts,the substrate scope as well as some preliminary structure-activity relationship and mechanism are discussed. | Deshuai Liu Boyu Liu Zexiong Pan Jianfeng Li Chunming Cui | 2019 | Science China Chemistry2019，62，5： | 1 |
| 11 | Simultaneous Optimization of Efficiency,Stretchability,and Stability in All-Polymer Solar Cells via Aggregation Control显示文摘With the emergence of Y-series small molecule acceptors,polymerizing the small molecule acceptors with aromatic linker units has attracted significant research attention,which has greatly advanced the photovoltaic performance of all-polymer solar cells.Despite the rapid increase in efficiency,the unique characteristics(e.g.,mechanical stretchability and flexibility)of all-polymer systems were still not thoroughly explored.In this work,we demonstrate an effective approach to simultaneously improve device performance,stability,and mechanical robustness of all-polymer solar cells by properly suppressing the aggregation and crystallization behaviors of polymerized Y-series acceptors.Strikingly,when introducing 50 wt%PYF-IT(a fluorinated version of PY-IT)into the well-known PM6:PY-IT system,the all-polymer devices delivered an impressive photovoltaic efficiency of 16.6%,significantly higher than that of the control binary cell(15.0%).Compared with the two binary systems,the optimal ternary blend exhibits more efficient charge separation and balanced charge transport accompanying with less recombination.Moreover,a high-performance 1.0 cm^(2)large-area device of 15%efficiency was demonstrated for the optimized ternary all-polymer blend,which offered a desirable PCE of 14.5%on flexible substrates and improved mechanical flexibility after bending 1000 cycles.Notably,these are among the best results for 1.0 cm^(2)all-polymer OPVs thus far.This work also heralds a bright future of all-polymer systems for flexible wearable energy-harvesting applications. | Kaihu Xian Kangkang Zhou Mingfei Li Junwei Liu Yaowen Zhang Tao Zhang Yong Cui Wenchao Zhao Chunming Yang Jianhui Hou Yanhou Geng Long Ye | 2023 | Chinese Journal of Chemistry2023，41，2： | 1 |

| 13 | High-entropy perovskite oxide BaCo_(0.2)Fe_(0.2)Zr_(0.2)Sn_(0.2)Pr_(0.2)O_(3-δ) with triple conduction for the air electrode of reversible protonic ceramic cells显示文摘Reversible protonic ceramic cells(RPCCs) show great potential as new-generation energy conversion and storage devices. However, the mature development of RPCCs is seriously hindered by the inactivity and poor stability of air electrodes exposed to concentrated vapor under operating conditions. Herein, we report a high-entropy air electrode with the composition BaCo_(0.2)Fe_(0.2)Zr_(0.2)Sn_(0.2)Pr_(0.2)O_(3-δ)(BCFZSP), which shows integrated electronic, protonic and oxygenic conduction in a single perovskite phase and excellent structural stability in concentrated steam. Such triple conduction can spread the electrochemically active sites of the air electrode to the overall electrode surface, thus optimizing the kinetics of the oxygen reduction and evolution reactions(0.448 Ω cm^(2) of polarization resistance at 550℃). As-prepared RPCCs with a BCFZSP air electrode at 600℃ achieved a peak power density of 0.68 W/cm^(2) in fuel-cell mode and a current density of 0.92 A/cm^(2) under a 1.3 V applied voltage in electrolysis mode. More importantly, the RPCCs demonstrate an encouragingly high stability during 120 h of reversible switching between the fuelcell and electrolysis modes. Given their excellent performance, high-entropy perovskites can be promising electrode materials for RPCCs. | Jiaxiang Sun Rongzheng Ren Hualiang Yue Wencan Cui Gaige Wang Chunming Xu Jinshuo Qiao Wang Sun Kening Sun Zhenhua Wang | 2023 | Chinese Chemical Letters2023，34，7： | 0 |

| 17 | Stable Au nanoparticles confined in boron nitride shells for optimizing oxidative desulfurization显示文摘Supported gold(Au)nanocatalysts have long played an important role in numerous heterogeneous catalysis.However,the dominant difficulty of poor thermodynamic stability hampers its practical application.Herein,a core–shell structured Au nanocatalyst with Au nanoparticles(NPs)confined in boron nitride(BN)shells is proposed for enhanced thermodynamic stability.The two-dimensional porous structure of BN not only functions as a physical separator for the sintering resistance of Au NPs,but also provides a microchannel for catalytic reaction substrates.Besides,owing to the confinement effect,a strengthened interaction between well-designed Au NPs and the BN can be expected,which further boosts the stability and catalytic activity.Detailed experiments show that a proper BN shell thickness is important to maintain the balance between the sintering resistance and catalytic activity.A significantly boosted performance of 97.2%conversion in oxidative desulfurization(ODS)was obtained with a proper number of BN coating layers,outperforming the one with a thicker BN shell.Moreover,the recyclability of the prepared catalyst was investigated with no obvious decrease in catalytic performance after 10 runs,greatly higher than that without a BN shell,suggesting excellent durability. | Linjie Lu Jing He Peiwen Wu Yang Sun Mingqing Hua Peng Cui Wenshuai Zhu Huaming Li Zhichang Liu Chunming Xu | 2023 | Nano Research2023，16，10： | 0 |
| 18 | Boosting methylcyclohexane dehydrogenation over Pt-based structured catalysts by internal electric heating显示文摘Methylcyclohexane(MCH)serves as an ideal hydrogen carrier in hydrogen storage and transportation process.In the continuous production of hydrogen from MCH dehydrogenation,the rational design of energy-efficient catalytic way with good performance remains an enormous challenge.Herein,an internal electric heating(IEH)assisted mode was designed and proposed by the directly electrical-driven catalyst using the resistive heating effect.The Pt/Al2O_(3)on Fe foam(Pt/Al2O_(3)/FF)with unique threedimensional network structure was constructed.The catalysts were studied in a comprehensive way including X-ray diffraction(XRD),scanning electron microscopy(SEM)-mapping,in situ extended X-ray absorption fine structure(EXAFS),and in situ COFourier transform infrared(FTIR)measurements.It was found that the hydrogen evolution rate in IEH mode can reach up to above 2060 mmol·gPt^(−1)·min^(−1),which is 2–5 times higher than that of reported Pt based catalysts under similar reaction conditions in conventional heating(CH)mode.In combination with measurements from high-resolution infrared thermometer,the equations of heat transfer rate,and reaction heat analysis results,the Pt/Al2O_(3)/FF not only has high mass and heat transfer ability to promote catalytic performance,but also behaves as the heating component with a low thermal resistance and heat capacity offering a fast temperature response in IEH mode.In addition,the chemical adsorption and activation of MCH molecules can be efficiently facilitated by IEH mode,proved by the operando MCH-FTIR results.Therefore,the as-developed IEH mode can efficiently reduce the heat and mass transfer limitations and prominently boost the dehydrogenation performance,which has a broad application potential in hydrogen storage and other catalytic reaction processes. | Wenhan Wang Guoqing Cui Cunji Yan Xuejie Wang Yang Yang Chunming Xu Guiyuan Jiang | 2023 | Nano Research2023，16，10： | 0 |
