This paper describes the photochemical deposition of platinum onto TiO 2 surface and the full characterization of the catalysts using BET, XPS and TEM techniques. The 1 and 3 wt. % Pt/TiO 2 catalysts reveal high activity with 70% and 96% of ␣-diastereoselectivity in the hydrogenation of the carbon-c
