A special photocatalytic NiO/Ag2S nanocomposite is synthesized by hydrothermal method. Combined the photocatalytic properties of both NiO and Ag2S, the NiO/Ag2S nanocomposite shows high photocatalytic properties in methylene orange degeneration tests. Through the experiment analysis, the high photocatalytic properties of NiO/Ag2S nanocomposite are attributed to the uniform mixing of these two materials and the induced n-p junction at the interfacial contact between the NiO and Ag2S phases. This work offers novel NiO/Ag2S nanocomposites which have great potential applications in visible light photocatalysis.
