水性电解质中电催化硝酸根还原合成氨的研究进展
Research progress of electrocatalytic reduction of nitric acid to synthesis of ammonia in aqueous electrolyte
摘要
Abstract
Ammonia(NH3)is not only the main component of nitrogen fertilizers but also serves as a high-energy-density carbon-free hydrogen storage medium,making it an important chemical substance in modern industry.Current-ly,industrial NH3 synthesis is still dominated by the traditional Haber-Bosch process.This process operates under high temperature and high-pressure conditions,consuming large amounts of fossil fuels and releasing large amounts of car-bon dioxide.In recent years,an increasing number of researchers have focused on electrochemical nitrogen reduction reaction(NRR)technology for NH3 synthesis driven by renewable energy.However,due to the high dissociation ener-gy of the N ≡ N bond and the low solubility of N2,the yield and Faradaic efficiency of electrochemical NRR are rela-tively low.Nitrate(NO3-)is a common nitrogen-containing pollutant.Because NO3-has high solubility and the N=O bond has low dissociation energy,it can serve as an ideal raw material for NH3 production.Starting from the mecha-nism of electrocatalytic nitrate reduction reaction(NO3RR),this review systematically introduces the current research status of NO3RR electrocatalysts and discusses various strategies for developing nitrate reduction catalysts.Finally,the challenges and prospects of electrocatalytic NO3-reduction technology are summarized to promote future green and sustainable large-scale NH3 synthesis.关键词
