Mono-dispersed nanometals could act as excellent cocatalysts. However, nanometals were apt to be oxidized and aggregated, and their activity was decreased. Herein, well-dispersed and small-sized Cu nanoparticles controlled by the mesoporous of TiO2 microspheres (TiO2 MS) were prepared. It was found that the Cu implanted into the hybrid (Cu–TiO2 MS) was mainly in the form of Cu0 with high dispersion and stability. Furthermore, the electron transfer can be significantly accelerated, the absorption of TiO2 can be improved, and the over-potential of hydrogen evolution was reduced. Thereby, it showed higher photocatalytic activity and good stability compared with those of the Cu-P25.
