摘要
In 2 S 3 /In 2 O 3 composites were fabricated by annealing using metal-organic framework (In-MOF) as precursor, following by sulfurization of In 2 O 3 . Structural characterization showed that two kinds of In 2 S 3 /In 2 O 3 with different morphologies were obtained by controlling the pH condition during the sulfurization process. Optical characterization results revealed that In 2 S 3 /In 2 O 3 heterojunctions display an evidently decreased visible light emission and enhanced visible light absorption compared with that of pure In 2 O 3 . The In 2 S 3 /In 2 O 3 heterojunction exhibited improved visible-light photocatalytic activities, the optimal composite (pH=2) showed the highest efficiency of 91.14%. The improvement of photocatalytic performance was attributed to the construction of heterojunction.
