摘要/Abstract

摘要：

挥发性有机物（VOCs）的去除是目前大气环境治理的主要方向。其中最广泛用于去除VOCs的方法是吸附法，吸附材料的选择是吸附法的关键环节。从分子筛作为吸附材料的角度出发，简单介绍了目前在吸附VOCs方面效果卓越的MCM-41、ZSM-5和NaY 3种分子筛，重点综述了其制备方法及其对各种VOCs的吸附效果。结果表明，分子筛比表面积、孔道、硅铝比、平衡阳离子都会对吸附效果产生影响，可通过负载贵金属或金属氧化物、表面改性处理、复合材料、结构调整等方式优化分子筛吸附性能。未来，高吸附量、高疏水性、绿色环保和低成本可再生的新型分子筛在VOCs的吸附方面将有更广阔的前景。

Abstract:

Trapping volatile organic compounds（VOCs） is currently the primary focus of atmospheric environmental management.Adsorption is one of the most widely used methods for removing VOCs，and the selection of adsorption material is the key link in adsorption method.From the perspective of adsorption materials of zeolites，three kinds of zeolites，MCM-41，ZSM-5 and NaY，which had excellent effects in adsorbing VOCs，were briefly introduced.The research progress on preparation methods and their adsorption effects on various VOCs were mainly reviewed.The results showed that the specific surface area，the pore channel，the silica-alumina ratio and the equilibrium cation of zeolites all affected the adsorption effect and that the performance of the zeolites could be optimized by loading precious metals or oxides，surface modification treatment，composite materials and structural adjustment.In the future，the new zeolites with high adsorption capacity，high hydrophobicity，green and low-cost regenerable would have a broader prospect application in the adsorption of VOCs.
