Abstract

Improvement of light harvesting and reaction kinetics is of great importance for achieving efficient solar-driven CO reduction. Here, a Ni modified low-crystalline Ni-Ge containing hydroxide with Lewis acid sites was synthesized in highly reductive NaBH solution and exhibited 9.3 μmol g h CO and 3.5 μmol g h CH generation rates under visible light irradiation, and even achieved a 3.8 μmol g h CO evolution under infrared light irradiation. The wide-spectrum light harvesting resulted from the light absorption from the localized surface plasmonic resonance of Ni nanoparticles. In addition, the Lewis acid can activate C[double bond, length as m-dash]O bonds to decrease the kinetic barriers of CO reduction. The design concept that rationally combines the advantages of expanding the spectral response and activating CO may offer a new strategy for efficient solar energy utilization.
