College of Chemistry and Chemical Engineering Xi'an University of Science and Technology Tsinghua Shenzhen International Graduate School Tsinghua University School of Chemical Engineering and Technology Xi'an Jiaotong University

The recent advances in carbon-supported single-atom catalysts (SACs) for electrochemical reactions are comprehensively reviewed. The development and advantages of carbon-supported SACs are briefly introduced, followed by a detailed summary of the synthesis strategies employed for various carbon-supported SACs, including vapor phase transport, high temperature pyrolysis,and wet chemical methods. Subsequently, the advanced characterization techniques for carbon-supported SACs are reviewed. The applications of carbon-supported SACs in diverse fields, such as oxygen reduction reaction, carbon dioxide reduction reaction, nitrogen reduction reaction, hydrogen evolution reaction, and oxygen evolution reaction are summarized. Special emphasis is given to the modification strategies enabling carbon-supported SACs to exhibit excellent electrocatalytic performance. Finally, the prospects and challenges associated with utilizing carbon-supported SACs for electrochemical reactions are discussed.

Two polyoxovanadoborates with over 100 nuclei assembled from a {V_(14)Co_(12)B_(72)} cluster

引用

Science China Chemistry 2024年第8期67卷 2578-2585页

作者： Shuang-Xue Wu Yu-Jiao Dong Yang Yang chao Qin Chun-yi Sun Wei Guan Xin-Long wang Zhong-Min Su Key Laboratory of Polyoxometalate and Reticular Material Chemistry of Ministry of Education Northeast Normal UniversityChangchun 130024China School of Chemistry and Environmental Engineering Changchun University of Science and TechnologyChangchun 130013China Key Laboratory of Advanced Materials of Tropical Island Resources Hainan UniversityHaikou 570228China

Combining theoretical prediction and experimental exploration, the first sandwich-type polyoxovanadoborate(POVB) with an odd number of nuclei, [V_(11)B_(26)O_(73)(OH)_(10)]^(8-)(1), was discovered under hydrothermal conditions. Density-functional theory(DFT)gives a rationalization for the existence of this structure and the structural feature is consistent with the {V_NB_(2N+X)}(X = 2, 4, 6, 8)general formula. Excitingly, when Co and 1,10-phenanthroline(phen) are introduced into the synthesis of vanadoborates system,a 100-nuclei [Co_6(phen)_(10)(H_(2)O)_8][V_(14)Co_(12)B_(72)O_(144)(OH)_(20)]·28H_(2)O(2) and a 102-nuclei [Co_6(phen)_(14)(H_(2)O)_(4)][V_(14)Co_(12)B_(72)O_(144)(OH)_(20)]·23H_(2)O(3) with the same core structure of [V_(14)Co_(12)B_(72)]^(12-)are obtained. The vase-shaped [V_(14)Co_(12)B_(72)] polyanion is a multilayered sandwich-type structure containing seven distinct structural layers and is the largest known POVB. Furthermore, 2demonstrates exceptional thermal and chemical stability and serves as an efficient and stable catalyst for the photoreduction of carbon dioxide.
