Evolution of adsorbates and photogenerated electrons produced during photocatalytic reactions on TiO2 was studied by an IR site-poisoning technique.  Hydroxyl group sites were identified to be responsible for photo-oxidation of ethanol to acetate and CO2.  Fundamental understanding of the ethanol reaction pathways could assist in the design of highly-efficient photocatalysists.
