摘　　要：挥发性有机化合物(VOCs)广泛存在于工业排放、汽车尾气、溶剂使用等多个领域,VOCs不仅对环境造成严重污染,还对人体健康构成威胁,因此,有效去除VOCs成为大气环境保护的重要课题。沸石分子筛孔道结构丰富,具有离子交换能力和良好的稳定性,生产成本低,且对气态分子具有择形性和吸附性等特点,已成为去除VOCs不可或缺的吸附剂或催化剂。从沸石分子筛的拓扑结构和成分的角度出发,综述了利用沸石分子筛作为吸附剂和催化剂去除VOCs的最新研究进展,重点讨论其拓扑结构、孔道结构、硅铝比、活性物种等因素对VOCs吸附和催化氧化性能的影响,并展望了沸石分子筛去除VOCs面临的机遇和挑战。Volatile organic compounds(VOCs)are pervasive in numerous sectors,such as industrial emissions,automobile exhaust,and solvent utilization.The presence of VOCs in the environment has been linked to significant environmental contamination and potential human health risks.Consequently,the effective removal of VOCs has emerged as a crucial aspect of atmospheric environmental protection.Zeolites have become the preferred adsorbents or catalysts for the removal of VOCs due to their rich pore structure,ion-exchange capacity and good stability,low production cost,as well as shape selectivity and adsorptive properties for gaseous molecules.From the perspective of structure and composition of zeolite molecular sieves,the latest research progress on the use of zeolites as adsorbents and catalysts for the removal of VOCs is reviewed,focusing on the effects of its topology,pore structure,Si/Al ratio,active species and other factors on the adsorption and catalytic oxidation performance of VOCs.Furthermore,the paper identifies the opportunities and challenges in the use of zeolites for the removal of VOCs.
