Chinese Journal of Catalysis, 2008•ElsevierThe anaerobic photocatalytic decomposition of formic acid to hydrogen on Pt/TiO2 was
studied by in situ FT-IR spectroscopy. The molecularly adsorbed formic acid species is
transformed to a formate species, and the formate species is transformed to carbonates
during this reaction. The addition of water vapor in the reaction system strongly accelerates
this photocatalytic reaction and promotes the H2 production efficiency. The possible
mechanism of the reaction is proposed.
