Abstract :
The best strategy for clean H2 production is development of efficient photocatalyst systems for water splitting into H2 and O2 gases. Copper oxide deposited on 1-D TiO2 nanobelts (TB) tested for photocatalytic water splitting in the presence of glycerol as scavenger under natural solar light irradiation. The influence of amount of Cu-loading and effect of calcination temperature on rate of H2 production is revealed. The preliminary results evidenced that enhanced photocatalytic activity of CuO/TB (CTB) and showed 5 folds higher amount of H2 production than TiO2 nanoparticles. This high activity is attributed to synergic function of TiO2 nanobelts and CuO as well.
