Abstract: With the development of photocatalytic technology, the research and exploration of photocatalytic properties of 2D materials have also attracted much attention. The photocatalytic performance of graphene oxide/WS2/Mg-doped ZnO (rGOWMZ) composites under 600 ℃ annealing is excellent because the degradation rate of Rhodamine B (RhB) is 99.6% under natural light, with the added 0.5% amount of In2Se3 sheets which is a direct bandgap semiconductor. The In2Se3 sheets prepared through liquid exfoliation are about 100 nm and ~5 atomic layers thickness. The composites are carried out with Transmission electron microscope (TEM), Atomic force microscope (AFM), X-ray diffraction (XRD), and Scanning electron microscope (SEM). And the rGOWMZ+In2Se3 composites exhibit excellent photocatalytic property, showing great potential in photocatalyst application.

Key words: In2Se3 sheets, 2D materials, natural sunlight, photocatalytic enhancement
