碳捕集耦合原位电催化转化技术研究进展
Research advances in integrated CO2 capture and in situ electrocatalytic conversion technologies
摘要
Abstract
[Objective]Carbon capture,utilization technology is a pivotal pathway for achieving CO2 emission reduction,yet its large-scale application is hindered by high energy consumption and costs.To address these challenges,the integrated carbon capture and in-situ electrocatalytic conversion technology has been proposed,which synergistically couples the two processes,avoids the regeneration of capture media and the release of CO2,improves energy efficiency,reduces production costs,and provides key technical support for carbon neutrality.Despite its promising potential,critical issues such as the reaction mechanism and the selection of capture media require in-depth investigation.[Methods]This article introduces the fundamental principles of integrated carbon capture and in-situ electrocatalytic conversion technology,systematically reviews and summarizes the characteristics of liquid-solid and gas-solid reaction systems,with a focus on analyzing research progress in systems such as amine solutions,and discusses the advantages,disadvantages,and key technical challenges of these reaction systems.[Results]Studies show that in liquid-solid reaction systems,amine-based systems are mature in CO2 capture but suffer from mass transfer limitations,leading to inferior electrolysis performance compared to conventional electrocatalytic reduction technologies.(Bi)carbonate solution systems can rival the performance of gas-phase electrolyzers,but the use of bipolar membranes results in high energy consumption and difficulties in downstream processing.Amino acid salt systems exhibit high CO2 absorption rates,low vapor pressure,and oxygen tolerance,yet remain underexplored.Ionic liquid systems enable efficient CO2 conversion even under ambient conditions but face challenges such as mass transfer limitations,difficult product separation,and high costs.In gas-solid reaction systems,porous nanomaterials such as MOFs and COFs offer advantages including directional regulation and enable direct adsorption-coupled in-situ electrocatalytic conversion.However,their industrial application is limited by issues such as insufficient selectivity and poor stability.[Conclusion]The liquid-solid reaction system and the gas-solid reaction system have their own advantages and disadvantages.The technical route can be optimized according to the actual situation.Future efforts should focus on screening electrolytes or catalysts that balance capture efficiency and electrolysis performance,optimizing electrolyzer design,and developing poisoning-resistant catalysts for complex flue gas environments,so as to promote the efficient integration and scalable application of carbon capture and electrocatalytic conversion.关键词
