Selective electrocatalytic nitrate reduction to dinitrogen: Mechanisms, catalysts, and challenges
Electrocatalytic reduction of nitrate to dinitrogen (N2) offers a sustainable, carbon-neutral approach to mitigate nitrate pollution by transforming nitrate into an environmentally benign end-product. While extensive research has focused on ammonia production, selective N2 production remains challenging due to complex pathways, limitations in detection, and the difficulty of controlling reaction on the electrocatalysts. This review provides an overview of current progress in this field, focusing on mechanistic insights, N2 detection methods, and advances in catalyst design. Various classes of electrocatalysts, including monometallic, bimetallic, and single-atom systems, oxide-based and carbon-based materials, examining how their structures regulate key intermediates and NN coupling. The influence of operational parameters such as applied potential, electrolyte, pH, and reactor design is also reviewed. Despite significant advances, challenges remain in understanding interfacial mechanisms and achieving high N2 selectivity under realistic conditions. This review aims to offer timely insights and guidance for the future development of efficient electrocatalytic systems toward selective nitrate-to-N2 conversion, advancing environmental remediation and sustainable nitrogen management.
期刊介绍:
Electrochemistry Communications is an open access journal providing fast dissemination of short communications, full communications and mini reviews covering the whole field of electrochemistry which merit urgent publication. Short communications are limited to a maximum of 20,000 characters (including spaces) while full communications and mini reviews are limited to 25,000 characters (including spaces). Supplementary information is permitted for full communications and mini reviews but not for short communications. We aim to be the fastest journal in electrochemistry for these types of papers.
