The principal objective of photoelectrocatalysis is to provide low-energy activation pathways for the passage of electronic charge carriers through the electrode electrolyte interface and, in particular, for the photoelectrochemical generation of chemical products.H. Tributsch, "Photoelectrocatalysis," in Photocatalysis: Fundamentals and Applications, N. Serpone and E. Pelizzetti, Eds., ed New York: Wiley-Interscience, 1989, pp. 339-383. With regard to photoelectrochemical oxidation, we may consider, for example, the following system of reactions, which constitute TiO2-catalyzed oxidation.O. Legrini, E. Oliveros, and A. Braun, "Photochemical processes for water treatment," Chemical Reviews, vol. 93, pp. 671-698, 1993.
