Abstract

Electrochemical nitrate reduction reaction (NO₃RR) is crucial in converting wastewater nitrate sources into value-added products under mild, low-cost conditions. Metals with highly occupied d-orbitals, such as Au, Ag, Cu, and Pt, are promising materials for high-performance electrocatalytic NO3- reduction due to their favorable surface electronic properties. While many metals are effective catalysts for NO₃RR, their limited ability to favor specific products often hinders practical application. This short review analyzes recent understanding of the reaction mechanisms and pathways of NO₃RR, focusing on the structural and electronic effects of the catalysts such as underpotential deposition systems and single-atom catalysts on product selectivity.

硝酸根离子电催化还原过程中结构、组成和选择性的关系
电化学硝酸还原反应(NO₃RR)是在温和、低成本的条件下将废水硝酸盐源转化为增值产品的关键。具有高占位d轨道的金属,如Au、Ag、Cu和Pt,由于其良好的表面电子性质,是高性能电催化还原NO3-的有前途的材料。虽然许多金属都是NO₃RR的有效催化剂,但它们对特定产品的催化能力有限,往往阻碍了实际应用。本文简要分析了近年来对NO₃RR反应机理和途径的认识,重点介绍了欠电位沉积体系和单原子催化剂等催化剂对产物选择性的结构和电子效应。

期刊介绍: The development of the Current Opinion journals stemmed from the acknowledgment of the growing challenge for specialists to stay abreast of the expanding volume of information within their field. In Current Opinion in Electrochemistry, they help the reader by providing in a systematic manner: 1.The views of experts on current advances in electrochemistry in a clear and readable form. 2.Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications. In the realm of electrochemistry, the subject is divided into 12 themed sections, with each section undergoing an annual review cycle: • Bioelectrochemistry • Electrocatalysis • Electrochemical Materials and Engineering • Energy Storage: Batteries and Supercapacitors • Energy Transformation • Environmental Electrochemistry • Fundamental & Theoretical Electrochemistry • Innovative Methods in Electrochemistry • Organic & Molecular Electrochemistry • Physical & Nano-Electrochemistry • Sensors & Bio-sensors •
