Abstract
Polynuclear aromatic hydrocarbons, such as acenaphthene, anthracene, fluorene and naphthalene, were found to undergo efficient photocatalytic oxidation in aqueous suspensions of TiO2 on irradiation with artificial light as well as sunlight. The rate of photo-oxidation was monitored by following the loss of fluorescence and oxygen uptake in these systems. 2-Formyl-3-hydroxycinnamaldehyde (7) and 5,8-dihydroxy-2,4-naphthaquinone (13) from naphthalene and anthraquinone (17) from anthracene were isolated during photo-oxidation. A mechanism involving hydroxyl and superoxide radicals has been proposed for the formation of the different intermediates in these cases.
