Abstract:

Conventional electrolytic systems (e.g., water electrolysis) which rely on the anodic oxygen evolution reaction (OER) are hindered by sluggish anodic kinetics and high energy demands. Electrocatalytic aldehyde oxidation, which has low oxidation potentials, has emerged as a promising anodic reaction to be coupled with a diversity of electroreduction reactions such as the hydrogen evolution reaction, oxygen reduction reaction, nitrate reduction reaction and carbon dioxide reduction reaction. This approach not only overcomes the limitations of traditional electrolysis but can also achieve production of H2 at the anode, thus enhancing the H2 production efficiency and energy utilization. In this minireview, we delve into the reaction mechanisms of electrocatalytic aldehyde oxidation, examining the interplay between low-potential and high-potential reaction pathways and their impact on reaction kinetics. Furthermore, we discuss the latest developments in catalyst design, with a focus on Cu and their alloys/composites, highlighting innovative strategies to improve catalytic efficiency, stability and selectivity. In terms of application, the coupling of electrocatalytic aldehyde oxidation not only holds significance for H2 generation but also offers new pathways for synthesizing valuable chemicals, thereby promoting the advancement of renewable energy and green chemistry. © The Royal Society of Chemistry 2025.
