In recent years,global warming caused by fossil fuel combustion and greenhouse gas emissions has become a growing concern,making the issue of CO2 capture and conversion the focus of global attention.Compared to conventional CO2 capture and separation technologies,membrane technology is highly attractive for its advantages in terms of separation efficiency and energy consumption.In particular,by combining membrane technology with catalytic reaction to prepare separation and reaction integrated composite membrane materials,CO2 can be effectively separated and converted into valuable chemicals in situ,thus realizing the goal of efficient resource utilization of CO2.This review first introduces the CO2 separation membrane separation mechanism and membrane materials.Then,the latest research results and development trend of CO2 membrane catalysis are introduced in conjunction with the membrane reactor.Finally,based on the ionic liquid system,the challenges and prospects for the development of integrated composite membrane materials for CO2 separation and reaction are discussed,with a view to providing references for researchers in related fields and promoting the development of CO2 emission reduction and resource utilization technologies.
