Abstract
The high total energy consumption of water electrolysis systems is often attributed to the slow kinetics of oxygen evolution reaction (OER). To address this issue, substituting small molecule oxidation reaction that is thermodynamically more advantageous for OER at the anode can significantly increase its energy conversion efficiency. Diversified oxidation substrates can ensure efficient conversion of the cathodic reaction while generating high value-added products or pollutant degradation at the anode. However, the complexity of the elemental composition of the substrate requires an in-depth study of the reaction mechanism. This review focuses on the mechanism of electrooxidation of different substrate molecules, such as ethanol, urea, and hydrazine. Additionally, it introduces some design ideas and strategies for high-performance electrocatalysts in conjunction with reaction path selectivity. The work also foresees the challenges in achieving industrial transformation in this field.
