This paper investigated the performance of photocatalysts of TiO2 nanotubes sensitized by photosensitizers of tetramethoxyphenylporphyrin(TMPP) for producing H2 from water under visible light. This photocatalyst might have a smaller band gap (2.6 eV). The investigation shows that a photosensitized catalyst combined TiO2 nanotube with TMPP can be used to extend the absorption of solar light region and enhance the efficiency of energy conversion, and the quantity of H2 evolution is 1.427 L m-2h-1g-1. It was a way to apply the dye sensitized TiO2 nanotubes photocatalyst in the visible light for clean energy.
