In-situ photo-deposition CuO1−x cluster on TiO2 for enhanced photocatalytic H2-production activity

The CuO1−x/TiO2 catalyst with only 1 wt% CuO1−x as a co-catalyst exhibited a high H2 evolution rate of 1725 μmol h−1 g−1, which reaches 120 times that of pure TiO2 under simulated solar light irradiation.139
