1Photoreduction of CO_2 to methanol over Bi_2S_3/CdS photocatalyst under visible light irradiation显示文摘The Bi2S3,CdS and Bi2S3/CdS photocatalysts were prepared by direct reactions between their corresponding salt and thiourea in a hy- drothermal autoclave.The photocatalytic activities of these photocatalysts for reducing CO2 to CH3OH under visible light irradiation have been investigated.The results show that the photocatalytic activity and visible light response of Bi2S3 are higher than those of CdS.The Bi2S3 modification can enhance the photocatalytic activity and visible light response of CdS.The photocatalytic activity of Bi2S3/CdS hetero-junction photocatalyst was the highest and the highest yields of methanol was 613μmol/g when the weight proportion of Bi2S3 to CdS was 15%,which was about three times as large as that of CdS or two times of that of Bi2S3.Xin Li Juntao Chen Huiling Li Jingtian Li Yitao Xu Yingju Liu Jiarong Zhou 2011Journal of Natural Gas Chemistry2011,20,4:11
2Heterogeneous reaction of NO_2 on the surface of montmorillonite particles显示文摘The studies on heterogeneous reactions over montmorillonite,which is a typical 2:1 layered aluminosilicate,will benefit to the understanding of heterogeneous reactions on clay minerals.Montmorillonite can be classified as sodium montmorillonite or calcium montmorillonite depending on the cation presented between the different layers.Using diffuse reflectance infrared Fourier transform spectroscopy(DRIFTS),the heterogeneous reaction mechanism of NO2 on the surface of montmorillonite was firstly investigated.Results showed that the reaction of NO2 on the surface of sodium and calcium montmorillonite fit a first-order kinetics,and the reaction duration of calcium montmorillonite was longer than that of sodium montmorillonite under the dry condition.For either sodium or calcium montmorillonite,the uptake coefficient decreased as humidity increased.Zefeng Zhang Jing Shang Tong Zhu Hongjun Li Defeng Zhao Yingju Liu Chunxiang Ye 2012Journal of Environmental Sciences2012,24,10:2

8Heat-treated glassy carbon under pressure exhibiting superior hardness,strength and elasticity显示文摘Glassy carbon(GC)is a type of non-graphitizing disordered carbon material at ambient pressure and high temperatures,which has been widely used due to its excellent mechanical properties.Here we report the changes in the microstructure and mechanical properties of GC treated at high pressures(up to 5 GPa)and high temperatures.The formation of intermediate sp2-sp3 phases is identified at moderate treatment temperatures before the complete graphitization of GC,by analyzing synchrotron X-ray diffraction,Raman spectra,and transmission electron microscopy images.The intermediate metastable carbon materials exhibit superior mechanical properties with hardness reaching up to 10 GPa and compressive strength reaching as high as 2.5 GPa,nearly doubling those of raw GC,and improving elasticity and thermal stability.The synthesis pressure used in this study can be achieved in the industry on a commercial scale,enabling the scalable synthesis of this type of strong,hard,and elastic carbon materials.Meng Hu Shuangshuang Zhang Bing Liu Yingju Wu Kun Luo Zihe Li Mengdong Ma Dongli Yu Lingyu Liu Yufei Gao Zhisheng Zhao Yoshio Kono Ligang Bai Guoyin Shen Wentao Hu Yang Zhang Ralf Riedel Bo Xu Julong He Yongjun Tian 2021Journal of Materiomics2021,7,1:1

12Extraordinary high-temperature mechanical properties in binder-free nanopolycrystalline WC ceramic显示文摘From the perspective of high-temperature applications,materials with excellent high-temperature mechanical properties are always desirable.The present work demonstrates that the binder-free nanopolycrystalline WC ceramic with an average grain size of 103 nm obtained by high-pressure and hightemperature sintering exhibits excellent mechanical properties at both room temperature and high temperature up to 1000℃.Specifically,the binder-free nanopolycrystalline WC ceramic still maintains a considerably high Vicker hardness H_(V)of 23.4 GPa at 1000℃,which is only 22%lower than the room temperature H_(V).This outstanding thermo-mechanical stability is superior to that of typical technical ceramics,e.g.SiC,Si_(3)N_(4),Al_(2)O_(3),etc.Nanocrystalline grains with many dislocations,numerous low-energy,highly stableΣ2 grain boundaries,and a relatively low thermal expansion coefficient,are responsible for the observed outstanding high-temperature mechanical properties.Hongfeng Dong Baozhong Li BoBo Liu Yang Zhang Lei Sun Kun Luo Yingju Wu Mengdong Ma Bing Liu Wentao Hu Julong He Dongli Yu Bo Xu Zhisheng Zhao Yongjun Tian 2022Journal of Materials Science & Technology2022,,2:1

19Hard nanocrystalline gold materials prepared via high-pressure phase transformation显示文摘As one of the important materials,nanocrystalline Au(n-Au)has gained numerous interests in recent decades owing to its unique properties and promising applications.However,most of the current n-Au thin films are supported on substrates,limiting the study on their mechanical properties and applications.Therefore,it is urgently desired to develop a new strategy to prepare nAu materials with superior mechanical strength and hardness.Here,a hard n-Au material with an average grain size of~40 nm is prepared by cold-forging of the unique Au nanoribbons(NRBs)with unconventional 4H phase under high pressure.Systematic characterizations reveal the phase transformation from 4H to face-centered cubic(fcc)phase during the cold compression.Impressively,the compressive yield strength and Vickers hardness(HV)of the prepared n-Au material reach~140.2 MPa and~1.0 GPa,which are 4.2 and 2.2 times of the microcrystalline Au foil,respectively.This work demonstrates that the combination of high-pressure cold-forging and the in-situ 4H-to-fcc phase transformation can effectively inhibit the grain growth in the obtained n-Au materials,leading to the formation of novel hard n-Au materials.Our strategy opens up a new avenue for the preparation of nanocrystalline metals with superior mechanical property.Chenlong Xie Wenxin Niu Penghui Li Yiyao Ge Jiawei Liu Zhanxi Fan Xiaoxiao Liu Ye Chen Ming Zhou Zihe Li Mengdong Ma Yonghai Yue Jing Wang Li Zhu Kun Luo Yang Zhang Yingju Wu Lin Wang Bo Xu Hua Zhang Zhisheng Zhao Yongjun Tian 2022Nano Research2022,15,7:0
