The article deals with the synthesis of highly active visible-light-driven nanocomposite for the decontamination of water hazards under sunlight-type excitation. The surface of visible-light-active nanostructured photocatalyst tungsten oxide (WO 3 ) was modified with noble metals, such as platinum (Pt) and gold (Au) nanoparticles, and the resulting photocatalytic activity of the nanocomposites...
The present study deals with the surface modification of nano-structured tungsten oxide (WO 3 ) with nanoparticles of platinum (Pt) by applying a novel laser-based photocatalytic process. Microscopic studies revealed that Pt particles were homogeneously dispersed with narrow size distribution (2–4nm) onto the surface of WO 3 within a short time of laser irradiation while XPS studies...
