• The WO3/WS2 nanostructures were successfully prepared using a two-step hydrothermal/gas phase method.
• The WO3/WS2 nanostructures obtained were coexistence of WO3 and WS2 in the same particle.
• The WO3/WS2 nanostructures showed excellent UV–visible optical absorption properties.
• The WO3/WS2 nanostructures may have a potential application as an UV–visible photocatalyst.
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.
Experimental study on the morphologies and the UV–visible absorption of WO3/WS2 nanostructures synthesized in H2S/H2 atmosphere by calcining a WO3·0.5H2O, and its photocatalytic reaction mechanism were presented in current work.Figure optionsDownload as PowerPoint slide
