| Abstract: | The WO3/WS2 nanostructures were successfully prepared using a two-step hydrothermal/gas phase method. The physical properties of the nanostructures were characterized using XRD, SEM, TEM, UV–visible spectroscopy. The WO3/WS2 nanostructures obtained were coexistence of WO3 and WS2 in the same particle. The WO3/WS2 nanostructures contained a wide and intensive absorption in the UV–visible light region of 245–750 nm, which showed that the WO3/WS2 nanostructures may have a potential application as an UV–visible photocatalyst. |
