The existence of heterogeneous photoassisted catalysis is defined by a simple criterion: the demonstrated formation of more than 100 monolayer equivalents of product. The kinetics and possible mechanism for the TiO2-photocatalyzed selective partial oxidation of alkanes to oxygenates (aldehydes and ketones) are reviewed, and data establishing the photocatalyzed mineralization of the chloromethane CHCl3 (chloroform) and the chloroethylene Cl2C = CClH (trichloroethylene) are presented. A brief final discussion concerns the possible formation of photocatalytically active solid phases in fly ash, and the relevance of these hydrocarbon and halocarbon conversions and other photocatalyzed conversions to atmospheric chemistry.
