石墨烯负载单原子钴催化剂的制备及其电催化二氧化碳还原反应性能
CoN4 active sites in a graphene matrix for the highly efficient electrocatalysis of CO2 reduction
摘要
Abstract
Developing highly selective, economical and stable catalysts for the electrochemical conversion of CO2 into value-ad-ded carbon products to mitigate both CO2 emission and the energy crisis is challenging. We report an efficient and robust electrocata-lyst for the CO2 reduction reaction (CO2RR) by embedding CoN4 active sites in a graphene matrix. These highly dispersed CoN4 sites show an extraordinary CO2RR activity, with a high CO Faradaic efficiency of nearly 95% at ?0.76 V (vs. RHE) and remarkable dur-ability. The corresponding overpotential is 0.65 V. Our finding could pave the way for the design at the atomic scale of highly effi-cient electrocatalysts for the CO2RR.关键词
