Review on electrocatalytic co-reduction of carbon dioxide and nitrate for urea synthesis
摘要
Abstract
Urea is a critical agricultural nitrogen fertilizer and an essential component for crop growth.Electrocatalytic co-reduction of CO2 and NO3-via C-N coupling to synthesize urea has emerged as a promising strategy for achieving clean and sustainable urea production,and has attracted considerable attentions.Compared to the traditional Bosch-Meiser process,the C-N coupling reaction offers potential for reduced energy consumption and lower carbon emissions.This review summarizes recent research progress in electrocatalytic co-reduction of CO2 and NO3-for urea synthesis,providing an in-depth discussion of the reaction mechanisms.By integrating in-situ characterization techniques and density functional theory calculations,this paper reveals the micro-level mechanisms that promote C-N coupling and enhance urea synthesis efficiency.Key catalyst design strategies to improve urea yields are also outlined,including heteroatom doping,defect engineering,heterostructure construction,alloying,and atomic-scale modulation.Finally,the challenges and prospects for future research and industrial applications are addressed,with a focus on achieving efficient,low energy consumption urea synthesis at large scale.It also analyzes the structural design and precise regulation of catalysts,providing theoretical and practical support for sustainable urea production.关键词
