Recent Progress in Electrocatalytic Conversion of CO₂ to Valuable C₂ Products

Converting CO2 into high value-added chemicals by renewable energy directly alleviates the problem of resource shortages, while also reduces amount in atmosphere. Among various reduction methods, electroreduction has attracted much attention because its moderate operating conditions and a green easy-to-scale strategy. In this work, four catalyst enhancement mechanisms: synergistic effect, strain ligand defect effect are briefly described. Then, catalytic mechanisms C2 products fully expounded, depending on number transferred electrons during process. addition, membrane electrode is introduced from three aspects ion exchange membrane, layer, gas diffusion layer. Finally, developing direction reaction proposed. This work provides an essential guide for design preparation catalysts summarized intrinsic catalysis mechanism, which beneficial to development conversion future.
