Advances in Electrocatalytic Nitrate Reduction: Insights into Mechanisms and Reaction Optimization

Abstract Electrocatalytic nitrate reduction (NO 3 RR) offers a promising approach to address nitrate pollution by converting harmful nitrates into environment‐benign or valuable products like nitrogen gas (N 2 ) or ammonia (NH 3 ). This review explores the mechanisms, challenges, and catalysts involved in NO 3 RR, highlighting the role of catalyst selectivity, stability, and external reaction conditions. The discussion also covers the environmental and economic benefits of NO 3 RR for water treatment, alongside potential future directions in scaling‐up, system integration, and expanding research into tackling related nitrogen‐based pollutants as well as real world applications.
