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[Sb_(4)S_(5)(S_(3))]·C_(5)H_(11)N(1)和(C_(5)H_(12)N)_(2)[In_(2)Sb_(2)S7](_(2))。2种化合物分别由{SbS_(3)}或{InS_(4)}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。
To explore the diversity of structure and optoelectronic applications of metal chalcogenide cluster materi-als,two Sb-based chalcogenide cluster compounds[Sb_(4)S_(5)(S_(3))]·C_(5)H_(11)N(1)and(C_(5)H_(12)N)_(2)[In_(2)Sb_(2)S7](_(2))have been syn-thesized through solvothermal method using asymmetric coordination geometry with Sbcontaining lone pair elec-trons and sulfur.The two compounds consist of combinations between{SbS_(3)}or{InS_(4)}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.CCDC:2310897,1;2310898,2.
