The titanate nanotubes (TNTs) composites enhanced the photocatalytic selectivity for H2 generation from formic acid better than Pt/TiO2. In addition, intensified electronic interactions occur between the components of TNTs and the Pt atoms in terms of the strong metal-support interaction, consequently influencing the behavior of photocatalysts. Therefore, the photocatalyst formed by Pt and TNTs has higher photocatalytic performance than TiO2 from a 20% v/v methanol solution under UV and visible light irradiation.
