摘要：

The photo-assisted carbon dioxide (CO2) hydrogenation provides an efficient and straightforward method for producing solar fuels with high efficiency. However, the development of highly efficient catalysts with controllable selectivity and long-term stability still faces major challenges. This study proves that solar energy can promote the CO2 hydrogenation over Cu/ZnO catalysts efficiently a atmospheric pressure and the selectivity of the reduction products can be controlled by varying the Cu/Zn molar ratio. Meanwhile, the hot electrons generated from Cu nanoparticles due to the surface plasmon resonance (SPR) and the photogenerated electrons from ZnO with light excitation can promote the H-2 cleavage and the activation of CO2.
