Book Description
The heterogeneous photocatalytic decomposition of adipic acid in deaerated aqueous solutions containing a suspension of platinized TiO2 (anatase) powder leads to the formation of CO2 and butane with lesser amounts of valeric acid and negligibly small quantities of oligomeric materials. A mechanism for this photo-Kolbe reaction, which yields different products than the electrochemical Kolbe reaction, is proposed. The photodecomposition of benzoic acid in oxygen-containing solution at platinized TiO2 was also investigated. The reaction product is predominantly CO2, with intermediate production of salicylic acid and phenol. A mechanism for the reaction based on photogeneration of hydroxyl radicals and adsorption of intermediates on the powder surface is proposed. (Author).
