CO2环加成用离子液体/金属有机框架催化材料研究进展OA

In order to address the global climate change challenge and achieve the"carbon neutrality"goal,carbon capture,utilization and storage(CCUS)technology has become a key approach to mitigate greenhouse gas emissions.Among them,capturing and converting CO2 into cyclic carbonates has significant economic and environmental advantages and is considered one of the most promising carbon capture and utilization technologies for industrial application.The mechanism of CO2 cycloaddition reaction with epoxides was reviewed,and the limitations of traditional catalytic systems,such as poor recyclability and lack of nucleophilic groups were pointed out.The synthesis methods of ionic liquid/metal-organic framework(IL/MOF)composite materials were emphasized,including in-situ encapsulation,pre-modification,and post-modification.The catalytic performances of IL/MOF composite materials were analyzed and the current challenges of poor stability,easy loss of active components and so on were pointed out.Future research should focus on constructing micro-mesoporous MOF carriers to fully utilize the structural advantages of multi-level pores for the purpose of further improving the catalytic performances of IL/MOF composite materials,and developing green,low-energy and efficient IL/MOF composite materials suitable for the chemical conversion of low-concentration CO2 mixed gases to meet the needs of practical industrial applications.
