A new series of tris-(bipyridyl)ruthenium-like complexes based on the 4-tripheylamine-2,2’:6’,2’’-terpyridine (TPA) push-pull ligand was prepared by incorporation of 4-carboxypyridine (cpy), 4,4’-dicarboxi-2,2’-bipyridine (dcbpy) and 4-ca

We report, for the first time, the photocatalytic activity of pure TiO2 P-25 in the form of thin homogeneous mesoporous films under visible light activation. The study was accomplished by analyzing the photodegradation rate of two water contaminant m

The concept of negatively charged electrostatic blocking barrier is demonstrated using benzotriazole (btzH) as ancillary ligands in a new ruthenium-dicarboxybipyridine photosensitizer, [Ru(dcbpyH)2(btzH)2], which was deprotonated in a stepwise manner

Nickel hydroxide nanoparticles with enhanced electrocatalytic activity and stability in the alpha phase were prepared by incorporation of 20 atom% of Ce(III) ions, that were shown to be oxidized to the catalytic active Ce(IV) species in the mixed hyd

The synergic effect observed in dye sensitized TiO 2 solar cells cannot be explained simply by the proportion of rutile and anatase nanoparticles in the mesoporous electrode. In fact, subtle differences in the surface chemical composition dramaticall
