Synthesis,structure,and electrocatalytic oxygen reduction reaction properties of metal antimony-based chalcogenide clusters
To explore the diversity of structure and optoelectronic applications of metal chalcogenide cluster materi-als,two Sb-based chalcogenide cluster compounds[Sb4S5(S3)]·C5H11N(1)and(C5H12N)2[In2Sb2S7](2)have been syn-thesized through solvothermal method using asymmetric coordination geometry with Sb(Ⅲ)containing lone pair elec-trons 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.CCDC:2310897,1;2310898,2.
