Abstract
The accumulation of nitrates in the environment causes serious health and environmental problems. The electrochemical nitrate reduction reaction (e-NO3RR) has received attention for its ability to convert nitrate to value-added ammonia with renewable energy. The key to effective catalytic efficiency is the choice of materials. Group VIII-based catalysts demonstrate great potential for application in e-NO3RR because of their high activity, low cost, and good electron transfer capability. This review summarizes the Group VIII catalysts, including monatomic, bimetallic, oxides, phosphides, and other composites. On this basis, strategies to enhance the intrinsic activity of the catalysts through coordination environment modulation, synergistic effects, defect engineering and hybridization are discussed. Meanwhile, the ammonia recovery process is summarized. Finally, the current research status in this field is prospected and summarized. This review aims to realize the large-scale application of nitrate electrocatalytic reduction in industrial wastewater.
硝酸盐在环境中的积累造成了严重的健康和环境问题。电化学硝酸盐还原反应(e-NO3RR)能够利用可再生能源将硝酸盐转化为高附加值的氨气,因而备受关注。有效提高催化效率的关键在于材料的选择。基于 VIII 族的催化剂具有高活性、低成本和良好的电子转移能力,因此在 e-NO3RR 中具有巨大的应用潜力。本综述总结了第八族催化剂,包括单原子、双金属、氧化物、磷化物和其他复合材料。在此基础上,探讨了通过配位环境调控、协同效应、缺陷工程和杂化等方法提高催化剂内在活性的策略。同时,对氨回收过程进行了总结。最后,对该领域的研究现状进行了展望和总结。本综述旨在实现硝酸盐电催化还原在工业废水中的大规模应用。
