    摘要: The first object of the invention is directed to a process for depositing TiO 2 on a substrate, comprising the steps of (a) providing a substrate, (b) performing said deposition with TiCl 4 and water by atomic layer deposition on said substrate; and (c) performing an annealing step. Said process is remarkable in that said step (b) is carried out at a temperature inferior to 50°C, and said step (c) is carried out at a temperature comprised between 450°C and 600°C in ambient air. The second object is directed to a photocatalyst comprising at least one layer of mesoporous hydrogenated TiO 2 on a substrate and obtainable by the process in accordance with the first object of the invention. The third object is directed to an use of said photocatalyst in a photocatalytic reaction performed under UV-visible light.
