Graphical Abstract:


A bottom-up-then-up-down route is proposed to construct graphene-ZnS nanoplates (GZnS NP). Graphene-ZnS with hierarchical structure (G-ZnS HS) is first prepared by a “bottom-up” route, and then is transferred to ZnS nanoplates through an “up-down” route by annealing at low temperature. Photocatalytic activity is investigated and the formation mechanism of G-ZnS NP is proposed. This work provides an effective method for large-scale synthesis of graphene-based two-dimensional nanostructures.

Keywords: Graphene, photocatalytic activity, G-ZnS HS, photocatalyst promoter, ZnS nanoplates, G-ZnS NP.
