Highly Active Photocatalyst of CuO_x Modified TiO₂ Arrays for Hydrogen Generation

The photocatalytic performance and the involved mechanism of copper-modified TiO2 have attracted a wide range of scientific interests in recent years. In this study, we fabricate CuOx/TiO2 photocatalysts by depositing Cu, Cu2O, and CuO on the surface area of hierarchical TiO2 arrays using magnetron sputtering method. These CuOx/TiO2 photocatalysts exhibit excellent photocatalytic performance with H2 generation rate of 30 mmol m–2 h–1 for...
