Structural Design and Performance of Electrocatalysts for Carbon Dioxide Reduction: A Review

With the advance of industrialization of human society, fossil energy has been overconsumed, and excessive carbon dioxide has been discharged into the atmosphere, resulting in energy crisis and environmental issues.The preparation of high value-added fine chemicals by electrocatalytic reduction of carbon dioxide is one of the directions to explore the establishment of artificial carbon cycle, which has attracted extensive attention in fundamental research and industrial applications.Structural design and preparation of electrocatalysts with high activity, selectivity and stability are of great significance to achieve efficient catalytic performance for carbon dioxide reduction.In recent years, many studies have reported the structural design ideas and application cases of catalyst and electrode materials, and remarkable progress has been made.In this review, the regulation strategies of catalyst structure and electrode structure are summarized from four aspects: size effect, surface characteristics, defect engineering and multi-stage structure, and the development of electrocatalytic carbon dioxide reduction is prospected.
