Advances in Cu-Based Electrocataysts for Nitrate Reduction to Ammonia
摘要
Abstract
Nitrates are one of the main sources of pollution in groundwater,posing a serious threat to human health.The traditional methods for treating nitrates have limitations of high energy consumption,heavy economic burdens,and poor removal efficiency.There-fore,it is crucial to find green and efficient removal methods.Electrocatalytic nitrate reduction not only purifies nitrate in wastewater,but also generates ammonia,which has broady attracted attention.However,the multi electron proton transfer step and competitive hy-drogen evolution reaction pose challenges for nitrate electroreduction.To improve ammonia yield and Faraday efficiency,it is necessary to continuously develop efficient and low-cost electrochemical nitrate reduction reaction(NO3RR)electrocatalysts.Cu-based electrocat-alysts have the advantages of low cost,abundant reserves,and inhibition of hydrogen evolution reactions,making them more suitable for large-scale applications.This article reviewed the current research status of Cu-based catalysts in electrocatalytic reduction of nitrates to ammonia.The catalysts were catalogued as follows:Cu-based single metal,Cu-based oxide,and Cu-based bimetallic electrocatalysts.Cu-based bimetallic catalysts exhibited unique electron transfer and chemical properties due to their bimetallic synergistic effect.This catalyst enhanced the adsorption capacity of nitric intermediates and active hydrogen in nitrate reduction,providing new ideas and im-provement directions for the design of Cu-based catalysts in the future.关键词
