Abstract
The 2D porous graphitic C3N4 nanosheets/SnS2 was synthesized by the simple in situ hydrothermal method. In this work, the 2D porous graphitic C3N4 nanosheets was prepared by pyrolysis method, and then SnS2 was grown on porous g-C3N4 sheets by the hydrothermal method. The visible light responsive characteristics were assessed by the degradation of methyl orange dye under visible light illumination and the results showed that the 2D porous g-C3N4 nanosheets/SnS2 heterostructure has a better photodegradation ability compared with the pure g-C3N4 and SnS2. The superior performance was attributed to the narrow band gap, higher surface area, unique 3D structure and interfacial transportation of charge carriers.
