Fabrication of indium sulfide/graphene oxide photodegradation of rhodamine B-containing wastewater under visible light irradiation

The fabrication of indium sulfide/graphene oxide composites (In₂S₃@GO) via a novel hydrothermal method was reported. The morphology of the composites showed that the daisy-like In₂S₃ structures were dispersed evenly on GO with large specific surface area. The photocatalytic performance of In₂S₃@GO was evaluated through photodegradation Rhodamine B. In₂S₃@GO exhibits higher photodegradation performance than that of pure In₂S₃. In addition, the composites showed great adsorption-desorption ability and stability. The solution pH value also has a significant influence on photocatalytic activity of In₂S₃@GO. This work may provide new insights to construct carbon-based semiconductor photocatalyst for organic dye pollution degradation. (paper)
