Design and Synthesis of TiO(2) Hollow Spheres with Spatially Separated Dual Cocatalysts for Efficient Photocatalytic Hydrogen Production

TiO(2) hollow spheres modified with spatially separated Ag species and RuO(2) cocatalysts have been prepared via an alkoxide hydrolysis–precipitation method and a facile impregnation method. High-resolution transmission electron microscopy studies indicate that Ag species and RuO(2) co-located on th...

description TiO(2) hollow spheres modified with spatially separated Ag species and RuO(2) cocatalysts have been prepared via an alkoxide hydrolysis–precipitation method and a facile impregnation method. High-resolution transmission electron microscopy studies indicate that Ag species and RuO(2) co-located on the inner and outer surface of TiO(2) hollow spheres, respectively. The resultant catalysts show significantly enhanced activity in photocatalytic hydrogen production under simulated sunlight attributed to spatially separated Ag species and RuO(2) cocatalysts on TiO(2) hollow spheres, which results in the efficient separation and transportation of photogenerated charge carriers.
