摘要
人类工农业活动导致环境中硝酸盐浓度升高,利用电催化技术将硝酸盐还原合成氨(NO_(3)RA)符合“双碳”政策,可达到去除硝酸盐污染和制备氨(NH_(3))的双重目的。该文综述了铜(Cu)基材料电催化硝酸盐还原的反应机理,从反应机理角度分析了不同Cu基催化材料优势性能的起源。围绕Cu单原子、单金属Cu、Cu基合金、Cu基氧化物和Cu基金属有机框架材料的大量研究实例,对不同Cu基催化材料催化NO_(3)RA反应的性能进行归纳总结。通过对Cu基材料催化NO_(3)RA反应影响因素的分析,针对目前存在的问题展开探讨,以期为未来Cu基催化剂电催化NO_(3)RA反应的开发与实际应用提供参考。
Nitrate concentration in the environment has been increasing due to human industrial and agricultural activities,and electrocatalytic technology for reduction of nitrate to ammonia is in line with the"two-carbon"policy,achieving the dual purpose of nitrate pollution removal and ammonia preparation.Herein,the reaction mechanism of electrocatalytic nitrate reduction by copper-based materials was reviewed,from which the root for the advantageous properties of different copper-based catalytic materials was analyzed.Meanwhile,the electrocatalytic performance of different copper-based catalytic materials was summarized based on analysis data obtained from a large number of research examples of copper monoatoms,monometallic copper,copper-based alloys,copper-based oxides and copper-metal organic frameworks.The influencing factors on nitrate reduction catalyzed by copper-based materials were discussed and the existing problems were pointed out to provide reference for future development and practical applications.
