ReviewSurface modification of metal materials for high-performance electrocatalytic carbon dioxide reduction
Progress and potential
Electrocatalytic CO2 reduction reaction (CO2RR), which can utilize renewable electricity to convert the greenhouse gas CO2 to high-value chemicals and fuels, provides a promising solution to solve environmental and energy problems simultaneously. Recently, surface modification has emerged as an effective strategy to enhance the catalytic performance of materials, especially metal materials, toward the CO2RR. In this review, three surface modification strategies of metal materials are summarized; i.e. surface molecular functionalization, surface elemental doping, and surface plasma treatment. Future efforts should focus on investigating the underlying mechanism of surface modification, fine modification of metal materials, and application of advanced technologies in surface modification. The development of surface modification will significantly promote the production of advanced CO2RR catalysts toward practical applications, benefiting the establishment of a sustainable society.
