摘要：

Electrocatalytic carbon dioxide reduction (CO2RR) enables CO2 transformation to valuable chemicals by applying electrical field under mild conditions. Coupling CO2RR with suitable anode reactions with lower thermodynamic potential can reduce cell voltage, produce valuable chemicals simultaneously at anode and cathode, and thus reach a higher energy efficiency. This article introduced the strategy for CO2RR coupled oxidation synthesis system, investigated the effect of electrolysis device such as electrolytic cell and ion exchange membrane on the CO2RR coupling electrocatalytic performance, summarized the types of electrocatalysts commonly used in CO2RR coupled oxidation synthesis system and overviewed the latest progress in CO2RR coupled with typical anodic oxidation reactions such as chlor-alkali reaction, and alcohols and nitrogenous organic compound oxidation. Finally, in view of the existing problems, such as high cost of anode catalyst, difficulty in separation and detection of anode products and low reactants conversion rate, it was proposed that developing more efficient, stable and cheaper anode catalyst, upgrading electrode structure and electrolysis device and expanding new CO2RR coupling systems were the future research directions. © 2021, Chemical Industry Press Co., Ltd.
