Abstract
A definition of photocatalysis is suggested. The ‘redox’ and ‘photolytic’ mechanisms are explained. For the redox photocatalytic processes guidelines are given for describing the fluid-semiconductor interface. The main ideas of the ‘collective’ and of the ‘localized’ approaches are outlined. The case of oxygen photoadsorption-photodesorption onto TiO2 is briefly outlined. The thermodynamic conditions for photoreactivity are stressed.
