Abstract

The decay kinetics of electrons and holes photogenerated in Pt/TiO₂ was studied by time-resolved infrared absorption spectroscopy in methanol vapor, water vapor, and a mixture of the two. The holes were exhausted within 50 ns in the presence of methanol and it was concluded that they attached directly to methanol-derived adsorbates without the aid of water-derived hydroxyl radicals.
