Synthesis of porous ZnS, ZnO and ZnS/ZnO nanosheets and their photocatalytic properties

摘要

Porous ZnS, ZnO and ZnS–ZnO nanosheets (NSs) are obtained by annealing ZnS(en)_0.5 (en = ethylenediamine) NSs under suitable conditions in air. The annealing temperature plays an important role. Porous hexagonal wurtzite ZnS, ZnS–ZnO and ZnO NSs are obtained at 400, 500 and 600 °C, respectively. ZnS–ZnO NSs exhibit the highest photocatalytic activity and good photocatalytic stability in the decomposition of organic dye molecule rhodamine B (RhB) under ultraviolet (UV) light illumination.
