摘 要:多相催化二氧化碳(CO_2)高效转化为高附加值的精细有机化学品和化工燃料,具有非常重要的研究价值和工业应用潜力。共价有机框架材料(Covalent Organic Frameworks,COFs)由于其高比表面积、有序的孔道结构、高化学和热稳定性、可控的催化位点等特性,在CO_2吸附和转化方面都展现出突出的优势。通过合理的策略从分子水平对其孔道或表面进行改性引入功能性物种或催化活性位点,能够有效实现其对特定反应的选择性调控并提供物质传输的有利微环境,因此COFs材料近年来在CO_2催化转化领域中得到了迅速的发展,也具有良好的应用前景。本文针对近几年COFs材料在CO_2转化为重要化学品的研究领域进行了简要的综述,总结当前存在的问题,并对COFs催化材料今后在CO_2转化领域的发展进行了展望。Heterogeneous catalytic conversion of carbon dioxide(CO2)into high value-added fine organic chemicals and chemical fuels has been indicated the important research value and industrial application potential.Due to their high specific surface area,ordered channel structure,excellent chemical and thermal stability,controllable catalytic sites,covalent organic frameworks(COFs)as an emerging class of organic materials,have exhibited outstanding advantages for adsorption and conversion of CO2.Specifically functional molecules or catalytic sites can be easily incorporated into the channel or surface of COFs by using rational strategy,which can efficiently and purposefully achieve the selective regulation for the specific reactions and provide a favorable microenvironment for substrates transport in reaction process.These merits thus can endow promising catalytic performance for heterogeneous catalysis,which greatly give rise to the rapid development and have a good application prospect for the catalytic conversion and utilization of CO2 over COFs catalysts.Therefore,this review briefly focuses on the advances of the conversion of CO2 into important fine chemicals and chemical fuels over COFs in recent years and proposes the key scientific issues involved in this field.Moreover,we also attempt to propose an outlook on the prospective developments for the CO2 conversion and utilization by using COFs catalytic materials.
