Two-dimensional (2D) nanosheets materials have attracted extensive attention because of their promising practical application and theoretical values. In order to enhance the photocatalytic activity of bulk C3N4, we designed a 2D fabrication in which g-C3N4 nanosheets was in the middle of MoS2/graphene layered structure. Here, we report an effective strategy to synthesize ternary g-C3N4/MoS2/graphene nanocomposite photocatalyst via an in-situ adsorption method, which exhibits superior photocatalytic activity owing to enhanced charge carrier separation via well-contacted interface and fast charge transfer pathway. This work indicates a new insight into the design of such 2D heterostructure and a promising cocatalyst strategy for designing a more efficient g-C3N4-based semiconductor photocatalyst toward degradation of organic pollutants.
