Spectral dependences of the effective quantum yield of H-2 and CO2 evolution from a Pt/TiO2 suspension in a 1 N H2SO4 solution were measured in the quantum energy range from 2.0 to 3.6 eV. It was found that the processes of H-2 and CO2 evolution proceeded simultaneously, and yet they exhibited different spectra. It was shown that the differences in these spectra can be due to the presence of two phases in titanium dioxide: TiO2 with the structure of anatase and that with the structure of rutile. The hi,oh-frequency border of the spectrum that is characteristic for the hydrogen evolution is near to 3.25 eV and corresponds to the edge of the absorption of TiO2 itself with the structure of anatase. Carbon dioxide began to evolve from suspension upon illumination by photons with an energy of similar to 3 eV, i.e., at the band of absorption of TiO2 with the structure of rutile. Long-term illumination of the suspension resulted in some reduction of the titanium dioxide surface and coke deposition. It was supposed that the hydrogen evolution observed was due to the dehydrogenation of organic impurities and coke deposition on the titanium dioxide surface.
