摘　　要：CO_(2)捕集与CO_(2)电催化还原技术是减少碳排放、提高碳的可再生循环利用率的重要途径.两种技术既独立存在,又可以作为碳循环周期中的上下环节相互结合,即先捕集并提纯混合气中的CO_(2),然后将收集到的高纯度CO_(2)进行电催化还原反应,将其进一步转化为更有用的化学品.本文首先总结了CO_(2)捕集技术的研究现状,然后考虑到甲酸作为目前经济和技术上最具潜力的还原产物,调研并汇总了近年来在CO_(2)电还原制甲酸领域中关于高效电催化剂的制备和反应器件设计方面取得的研究进展.针对两种技术的研究现状,最后提出加快和开发新型碳捕集与利用技术,开发低成本、高效、稳定的电催化剂和设计具有低欧姆电阻、高转化能效的反应器等可以作为未来的研究重点和发展方向.Given that CO_(2) is the predominant greenhouse gas,its excessive emission has resulted in unprecedented climate change,necessitating the implementation of specific measures to mitigate atmospheric CO_(2) levels.CO_(2) capture and CO_(2) electroreduction represent two pivotal approaches for reducing carbon emissions and improving the sustainable utilization of carbon resources.These two technologies exist independently,but can also be synergistically integrated as the upper and lower components of the carbon cycle.Initially,CO_(2) in the mixture is captured and purified,followed by carrying out an electrocatalytic reduction reaction on the collected high-purity CO_(2) to further transform it into more useful chemicals.This review comprises three sections:(1)The review provides a comprehensive overview of the current research advancements in CO_(2) capture technology,which plays a pivotal role in the development of carbon capture,utilization,and storage(CCUS)technology.The CO_(2) capture technology can be categorized into absorption,adsorption,membrane separation and low-temperature methods.The chemical absorption method stands out as one of the most extensively employed and commercially viable technologies.The underlying principle involves the utilization of alkaline chemical absorbents to initiate a reaction with CO_(2),resulting in the formation of unstable salt products(such as carbonate,carbamate,etc.)in either liquid or solid phases.These generated salts can subsequently undergo decomposition under specific conditions,which can realize the separation and enrichment of CO_(2) and the regeneration of the absorbent.In addition,the pressure swing adsorption method is widely used in industrial CO_(2) separation,leveraging the reversible adsorption phenomenon of CO_(2) by an adsorbent,i.e.,adsorption at a higher pressure,desorption at a lower pressure or vacuum,to effectively isolate it from other components.This method is a more suitable physical adsorption technology for carbon capture in power plants,and it als
