Mechanism dye sensitization

Watanabe et al. have reported similar action spectrum analysis of photoin-duced degradation of Rhodamine B with a cadmium sulfide suspension and pointed out a similar dye-sensitization mechanism Watanabe, T. Takizawa, T. Honda, K. J. Phys. Chem. 1977, 81, 1845. Photocatalytic reaction of MB in aerated titania suspensions was reported in 1937 by a Japanese photochemist Horio, M. Nihon Gakujutsu Kyokai Hokoku 1937, 12, 204 (in Japanese). As far as the author knows, this is the first report on titania photocatalysis. 

In the remainder of this section we briefly overview fundamental concepts, vocabulary, photoelectrochemical characterization techniques and the dye-sensitization mechanisms developed for planar electrodes. We end the section with a short literature review of dye-sensitization studies.
