摘要：

Pt/TiO2 nanospheres and nanorods were used to generate hydrogen via water splitting and the effect of the shapes of TiO2 nanoparticles were evaluated for hydrogen evolution. TiO2 nanorods exhibited an increase in charge transfer rate between the nanoparticle surface and the electrolyte. This led to improvement in the rate of photo-catalytic hydrogen evolution during the decomposition of water.
