Abstract | Investigations on the interaction of hydrogen with platinum-containing titania have shown that the adsorption of spilt-over hydrogen (H*) species is connected with a partial electron transfer from H* to TiO2. The experimental results depict an enhanced n-type conductivity as well as a formation of neutral oxygen vacancies (V-OX(X)) from singly ionized vacancies (V-OX(+)) in the surface region of the semiconducting metal oxide. The influence on the electronic state of the oxygen vacancies was concluded from fluorescence measurements by means of FT NIR Raman spectroscopy |
