Abstract

Unsupported transparent nanoporous-nanocrystalline TiO2 membranes are prepared which are 20 μm thick anatase structures and have an associated surface roughness of ca. 1100. Visible-light induced charge injection by the adsorbed ruthenium complex, [bis(4,4′-dicarboxy-2,2′-bipyridine)(4,4′-dimethyl-2,2′- bipyridine)ruthenium(II)] dichloride 1, has been demonstrated for these membranes. Also demonstrated has been blue-light induced reduction of the adsorbed viologen, 1-ethyl-1′-[4-carboxy-3-hydroxyphenyl)methyl]-4,4′-bipyridinium perchlorate 2.
