摘要：A simple cadmium sulfide nanomaterial is found to be an efficient and stable electrocatalyst for CO2 reduction in aqueous medium for more than 40 h with a steady CO faradaic efficiency of approximately 95%. Moreover, it can realize a current density of -10 mA cm(-2) at an overpotential of -0.55 V on a porous substrate with similar selectivity. Theoretical and experimental results confirm that the high selectivity for CO2 reduction is due to its (0002) face with sulfur vacancies that prefers CO2 molecule reduction in aqueous medium.
