TL;DR: In this paper, the photocatalytic oxidation of benzyl alcohol and its derivatives, such as 4-methoxybenzyl alcohol, 4-chlorobenzyl alcohol (CB), 4-nitrobenzinzyl al alcohol (NB), 4-(trifluoromethyl) benzyl (TRB) alcohol, and 4-tertiary-butyl-benzymethyl alcohol (TBBA), into corresponding aldehydes was investigated under both UV and visible light irradiation.

TL;DR: In this paper, the photocatalytic activity for the formation of the aldehyde was evaluated by a pseudo-first-order reaction, and it was found that the activity is enhanced by phenyl-ring substitution with the electron-releasing groups (OCH3, CH3, C(CH3)3), electron-withdrawing groups (Cl, CF3 and NO2), leading to further reactions to form corresponding aldehydes.

TL;DR: In this paper, morphology, structure, fundamental absorption edge and photocurrent response of hybrid WO3/TiO2 films were investigated, and it was found that the band gap excitation of WO 3/Ti 2 caused effective charge separation to generate high anodic photocurrent by the oxidation of oxalic acid.

TL;DR: In this article, the authors review recent advances of TiO2-based visible-light-sensitive photocatalysts, classified by the origins of charge separation photo-induced in (1) bulk impurity (N-doping), (2) hetero-junction of metal (Au NPs), and (3) interfacial surface complexes (ISC) and their related photocATalysts.

TL;DR: The photocatalytic oxidation of benzyl alcohol into benzaldehyde proceeded with high conversion and selectivity on a TiO2 photocatalyst by O2 under visible light irradiation as mentioned in this paper.
