Electrochemical refinery, substituting the oxygen evolution reaction with thermodynamically favorable anode oxidation reactions coupled with cathode reduction reactions, is an emerging cost-effective strategy for the maximal utilization of electrical energy alongside the production of high-value chemicals for economic benefits and high efficiency. However, a summary and coherent perspective on the advances in electrochemical refinery have been long overdue. This review systematically sums up the recent advances and innovative strategies in electrochemical refinery aimed at enhancing economic benefits. Specifically, sacrificial-agent oxidation reaction coupling reduction reactions can achieve pollutant degradation and improve energy efficiency, while electrochemical synthesis reaction coupling reduction reactions can generate value-added products on both sides. Further, catalyst designs, specific reaction mechanisms, and cell configurations are discussed in detail. Finally, we showcase new insights on the current challenges and future perspectives on the development of coupled systems and hope to inspire further innovative work in this rapidly growing field.
