| 1 | Sulfonate group modified Ni catalyst for highly efficient liquid-phase selective hydrogenation of bio-derived furfural显示文摘The liquid-phase furfural(FAL) hydrogenation to furfuryl alcohol(FOL) and tetrahydrofurfuryl alcohol(THFOL) was investigated using sulfonate group(-SO3 H) grafted activated carbon(AC) supported Ni catalyst, which was prepared and activated simultaneously by liquid phase reduction method. This functionalized nickel catalyst demonstrated an enhanced catalytic performance for selective hydrogenation of FAL, in which almost 100% FOL(<80℃) and THFOL(>100℃) selectivity with complete conversion was obtained, respectively. More importantly, the conversion of transfer hydrogenation of FAL to FOL also can reach almost 100% under optimal conditions(140℃, 4.0 h). The effect of-SO3 H was evaluated and systematically analyzed by the combination of reaction performance and physico-chemical characterizations. Cycling test proved the prepared catalyst could be recycled and reused for several times without noticeably reducing catalytic activity of hydrogenation. | Wanbing Gong Chun Chen Haojie Wang Ruoyu Fan Haimin Zhang Guozhong Wang Huijun Zhao | 2018 | Chinese Chemical Letters2018，29，11： | 4 |
| 2 | Synergistic catalysis of cluster and atomic copper induced by copper-silica interface in transfer-hydrogenation显示文摘To data,using strong metal-support interaction(SMSI)effect to improve the catalytic performance of metal catalysts is an important strategy for heterogeneous catalysis,and this effect is basically achieved by using reducible metal oxides.However,the formation of SMSI between metal and inert-support has been so little coverage and remains challenge.In this work,the SMSI effect can be effectively extended to the inert support-metal catalysis system to fabricate a Cu^(0)/Cu-doped SiO_(2) catalyst with high dispersion and loading(38.5 wt.%)through the interfacial effect of inert silica.In the catalyst,subnanometric composite of Cu cluster and atomic copper(in the configuration of Cu-O-Si)can be consciously formed on the silica interface,and verified by extended X-ray absorption fine structure(EXAFS),in situ X-ray photoelectron spectroscopy(XPS),and high-angle annular dark field-scanning transmission electron microscopy(HAADF-STEM)characterization.The promoting activity in transfer-hydrogenation by the SMSI effect of Cu-silica interface and the synergistic active roles of cluster and atomic Cu have also been revealed from surface interface structure,catalytic activity,and density functional theory(DFT)theoretical calculation at an atomic level.The subnanometric composite of cluster and atomic copper species can be derived from a facile synthesis strategy of metal-inert support SMSI effect and the realistic active site of Cu-based catalyst can also been identified accurately,thus it will help to expand the application of subnanometric materials in industrial catalysis. | Ruoyu Fan Yange Zhang Zhi Hu Chun Chen Tongfei Shi Lirong Zheng Haimin Zhang Junfa Zhu Huijun Zhao Guozhong Wang | 2021 | Nano Research2021，14，12： | 3 |

| 5 | INFLUENCE OF INTERFACIAL STRENGTH ON THE FRACTURE TOUGHNESS OF GLASS-CERAMIC MATRIX COMPOSITEST显示文摘Nine kinds of glass-ceramic matrix composites with different compositions and inter facial strength(L) were prepared. The influence of Ti on the fracture toughness (K1c.) of composites was studied. It was discoved that, for the system no chemical reaction taking place at the interface, K1c. increased proportionallywith ts increasing at the first stage, then decreased when ts reached a certain value. According to this result,a model of relationship between L, thermal mismatch (Δαr) and K1c was built up. If a chemical reaction tookplace and a new phase was formed in the interface, the K1c. of composite was effected by the combination ofrs, chemical bonding, radial inter facial stress and other factors. | Wang Lingsen Liu Ruoyu Zang Jinsen Fan Yi(PowderMetallurgy Research institute, Central South University ofTechnology, Changsha 410083, China) | 1997 | Journal of Central South University1997，9，1： | 0 |

| 8 | Effect of Pyrophyllite Addition on Properties of Lightweight Insulation Refractory Materials显示文摘To solve the problem of over-high density of lightweight insulation refractory bricks prepared with fly ash,new lightweight insulation refractory materials with density < 0. 89 g·cm^(-3) were synthesized using pyrophyllite,fly ash,and Suzhou clay as the main starting materials and saw dust as the pore forming substance,and controlling the addition of the pyrophyllite( 20%,30%,and 40% by mass) and the treating temperature( 1 250,1 300,1 350,and 1 400 ℃). The synthesized materials were characterized by the XRD,SEM and the thermal conductivity measuring instrument. The results show at pyrophyllite addition of 30% and treat temperature of 1 400 ℃,the material can achieve linear shrinkage of 6. 6%,apparent porosity of 57%,bulk density of 0. 75 g·cm^(-3),compressive strength of 2. 7 MPa,and thermal conductivity at 350 ℃ of 0. 152-0. 216 W·( m·K)^(-1). This indicates that the pyrophyllite decomposition at high temperatures forms mullite and amorphous quartz introducing volume expansion,which counteracts some shrinkage at high temperatures.So it is feasible to use pyrophyllite,fly ash waste and clay to prepare lightweight insulation refractory materials. | CHEN Ruoyu LI Yuanbing XIANG Ruofei LI Shujing FAN Xiafei LI Yawei SANG Shaobai | 2017 | China's Refractories2017，26，3： | 0 |

| 12 | Outer delocalized electron aggregation of bromide bridged core–shell CuBr@C for hydrogen evolution reaction显示文摘Modulation of the surface electron distribution is a challenging problem that determines the adsorption ability of catalytic process.Here,we address this challenge by bridging the inner and outer layers of the core–shell structure through the bridge Br atom.Carbon shell wrapped copper bromide nanorods(CuBr@C)are constructed for the first time by chemical vapour deposition with hexabromobenzene(HBB).HBB pyrolysis provides both bridge Br atom and C shells.The C shell protects the stability of the internal halide structure,while the bridge Br atom triggers the rearrangement of the surface electrons and exhibits excellent electrocatalytic activity.Impressively,the hydrogen evolution reaction(HER)activity of CuBr@C is significantly better than that of commercial N-doped carbon nanotubes,surpassing commercial Pt/C at over 200 mA·cm^(−2).Density functional theory(DFT)calculations reveal that bridge Br atoms inspire aggregation of delocalized electrons on C-shell surfaces,leading to optimization of hydrogen adsorption energy. | Tianyi Xu Ruoyu Li Lei Zhang Dongxu Jiao Yilong Dong Ming Gong Dantong Zhang Jinchang Fan Dewen Wang Yanhua Liu Xiao Zhao Wei Zhang Weitao Zheng Xiaoqiang Cui | 2023 | Nano Research2023，16，5： | 0 |
