Abstract

Methanol is an available, small, and colorless molecule, which can be used for the photocatalytic activityevaluation without the sensitization problem associated with most dye molecules. Thus, TiO

₂ suspendedin aqueous methanol solutions is commonly employed as a model test for the photocatalytic degradationof organic pollutants in aerobic system or for photocatalytic hydrogen production in absence of molecularoxygen. It is, hence, important to explore the mechanism of its photocatalytic and photoelectrochemi-cal oxidation on TiO

₂ in aqueous solution. In this mini-review, the possible mechanisms for water andmethanol oxidation on TiO

₂ will therefore be presented and discussed.
