摘要：
A surface oxygen-injection strategy is proposed to synergistically modulate the electronic structure of the SnS2 nanosheets, thereby regulating the oxophilicity of the catalyst surface.The surface oxygen doping facilitates the CO2 activation and enhances the affinity for HCOO* species.The oxygen-injection SnS2 nanosheets exhibit a remarkable Faradaic efficiency of 91.6% for carbonaceous products with a current density of 24.1 mA cm−2 at -0.9 V vs RHE.
