在温和的溶剂热条件下，合成了两种新型的铟硫属锑酸盐及其四元混合固溶体[In 2Sb 2S 7-xSex] n2 n −.随着Se比例的增加，这些化合物的光学吸收边发生红移，并且随着光学响应从紫外光区转移到可见光区，表现出可调的光催化活性，用于降解橙子（MO）。
Two novel indium chalcogenidoantimonates and their quaternary mixed solid solutions with a layered structure of [In2Sb2S7-xSex]n2n− are successfully synthesized under mild solvothermal conditions. The compounds show a red-shift of their optical absorption edges and exhibit tunable photocatalytic activity for degradation of methyl orange (MO) with a shift of optical response from UV to the visible light region, as the proportions of Se increase.
