Coupling electrochemical CO2 reduction with value-added anodic oxidation reactions: progress and challenges

Abstract

Converting CO2 into chemicals using renewable electricity provides a promising avenue to realize carbon neutrality. Substituting the anodic oxygen evolution reaction by thermodynamically more favourable oxidation reactions with value-added products can significantly lower the cell voltage and enhance the output value of overall CO2 electrolysis. In this review, we summarize the up-to-date breakthroughs in electrochemical systems featuring the CO2 reduction reaction (CO2RR) coupled with various anodic oxidation reactions. Moreover, major challenges with possible solutions and future prospects in this field are pointed out, which are expected to benefit researchers and propel this coupling strategy to industrial applications.
