This review highlights the importance of integrating anode and cathode reactions for efficient use of electrical energy in electrocatalysis conversion processes, as well as the production of high-value substances. It provides a comprehensive overview of recent advances in co-electrolysis processes for valuable chemical production, discussing popular reactions such as hydrogen evolution and carbon dioxide reduction integrated with anodic oxidation reactions. Additionally, challenges and future prospects for these integrated reactions are proposed to benefit researchers and facilitate progress in the field.
To make efficient use of electrical energy in the whole electrocatalysis conversion process, the integrating of anode and cathode reactions plays a vital role. The combination of electrocatalytic anodic oxidation with cathodic reduction can not only maximize the return of energy investment, but also produces value-added materials on both sides. Herein, in this review, recent advances in co-electrolysis processes for valuable chemical production are systematically summarized. To be more specific, the popular hydrogen evolution reaction, carbon dioxide reduction reaction, nitrogen reduction reaction as well as nitrate reduction reaction integrated with anodic oxidation reactions to value-added products, respectively are comprehensively reviewed, and then other paired electrolysis systems (especially for biomass-based compounds) toward high-value-added chemical generation are discussed in detail. This review sheds light on the integration of electrocatalytic reductions and oxidation reactions to develop high-value substances. To benefit researchers and facilitate the progress in this field, the challenges and future prospects for these integrated reactions are also proposed.
