摘要: 为探索金属硫族团簇材料的多样性结构及其光电应用,利用溶剂热法,以含孤对电子的金属Sb(Ⅲ)与硫元素采用不对称的配位几何方式结合,合成了Sb基硫族团簇化合物 [Sb4S5(S3)]·C5H11N (1)和(C5H12N)2[In2Sb2S7] (2)。2种化合物分别由{SbS3}或{InS4}配位单元之间以顶点共享的方式组合而成。电催化氧还原反应(ORR)研究表明,化合物2的极限电流密度和半波电位均高于化合物1,表明其ORR性能更好。Koutecky-Levich图分析表明,由混合金属构筑而成的层状化合物2的ORR催化过程以四电子路径为主。

Abstract: To explore the diversity of structure and optoelectronic applications of metal chalcogenide cluster materials, two Sb-based chalcogenide cluster compounds [Sb4S5(S3)]·C5H11N (1) and (C5H12N)2[In2Sb2S7] (2) have been synthesized through solvothermal method using asymmetric coordination geometry with Sb(Ⅲ) containing lone pair electrons and sulfur. The two compounds consist of combinations between {SbS3} or {InS4} coordination units in a vertex-sharing manner, respectively. The electrocatalytic oxygen reduction reaction (ORR) studies showed that the limit current density and half-wave potential of compound 2 were higher than those of compound 1, indicating better ORR performance. The Koutecky-Levich plot analysis showed that the ORR catalytic process of layered compound 2 constructed from mixed metals is mainly through a four-electron pathway.
