| 1 | Chlorine doped graphitic carbon nitride nanorings as an efficient photoresponsive catalyst for water oxidation and organic decomposition显示文摘Rationally engineering the microstructure and electronic structure of catalysts to induce high activity for versatile applications remains a challenge. Herein, chlorine doped graphitic carbon nitride(Cl-doped g-C3N4) nanorings have been designed as a superior photocatalyst for pollutant degradation and oxygen evolution reaction(OER). Remarkably, Cl-doped g-C3N4 nanorings display enhanced OER performance with a small overpotential of approximately 290 m V at current density of 10 m A cm^-2 and Tafel slope of 83 m V dec-1, possessing comparable OER activity to precious metal oxides RuO2 and IrO2/C. The excellent catalytic performance of Cl-doped g-C3N4 nanorings originates from the strong oxidation capability,abundant active sites exposed and efficient charge transfer. More importantly, visible light irradiation gives rise to a prominent improvement of the OER performance, reducing the OER overpotential and Tafel slope by 140 m V and 28 m V dec^-1, respectively, demonstrating the striking photo-responsive OER activity of Cl-doped g-C3N4 nanorings. The great photo-induced improvement in OER activity would be related to the efficient charge transfer and the·OH radicals arising spontaneously on CN-Cl100 catalyst upon light irradiation. This work establishes Cl-doped g-C3N4 nanorings as a highly competitive metal-free candidate for photoelectrochemical energy conversion and environmental cleaning application. | Er-Xun Han Yuan-Yuan Li Qi-Hao Wang Wei-Qing Huang Leng Luo Wangyu Hu Gui-Fang Huang | 2019 | Journal of Materials Science & Technology2019，35，10： | 2 |

| 5 | Atomistic simulation on the generation of defects in Cu/SiC composites during cooling显示文摘The coefficient of thermal expansion(CTE)mismatch between the reinforcement and the matrix results in thermal residual stresses and defects within metal-matrix composites(MMCs)upon cooling from the processing temperature to ambient temperature.The residual stresses and thermally induced defects play an important role in the mechanical properties of MMCs,it is critical to understand the mechanism of defect formation and evolution.This study provides atomistic simulations to reveal the generation of thermal residual stresses,dislocation and incomplete stacking fault tetrahedron(ISFT)during cooling in the idealized Cu/SiC composites.We found that dislocations are generated explosively in a certain temperature range during cooling,which results in a non-linear relationship between dislocation density and temperature.The combined effect of the stresses induced by CTE mismatch and the thermodynamic state of the metal leads to the rapid generation of dislocations.The Shockley partial and the highly stable stair rod are the two dominant dislocation structures.The immobile stair-rod dislocations and the highly stable ISFTs formed in the initial high temperature stage inhibit further development of plastic deformation.The present results provide new insights into the defect formation mechanism and the dislocation strengthening mechanism of MMCs caused by thermal mismatch between constituents. | Yongnan Xiong Wangyu Hu Yao Shu Xing Luo Zhibo Zhang Jiazhen He Cuicui Yin Kaihong Zheng | 2022 | Journal of Materials Science & Technology2022，，28： | 1 |
