摘要: The great bottleneck that lies in CO 2 reduction reaction (CO 2 RR) electrocatalysts is to simultaneously enhance their conductivity and density of active sites. Herein, we developed a black reduced porous SnO 2 nanosheets electrocatalyst that enabled possessing both metallic conductivity and high density of active sites via vacancy engineering. The black reduced porous SnO 2 nanosheets showed high activity and selectivity for CO 2 RR to formate, with maximum Faradaic efficiency (FE) of 92.4% at the low overpotential of 0.51 V …
