Highly UV driven WOx@ZnO nanocomposites were synthesized by liquid impregnation (LI) method. The presence of WOx particles on the surface of ZnO nanorods were verified by TEM and EDX mapping. In addition, the XPS analysis shows that the WOx nanoparticles were a mixture of WO2 and WO3 nanoparticles. The photocatalytic enhancement of WOx@ZnO nanocomposites in degrading RhB dye under UV light suggests that deposition of WOx could have pro-longed the separation of electrons (in WOx) from the holes. More holes were able to diffuse to the surface of photocatalyst and directly oxidized the RhB dye molecules into less harmful by-products.
