For years, the serious air pollution, especially the haze, photochemical smog, and ozone, has attracted widespread attention at home and abroad. Volatile organic gases (VOCs) are important pollutants that cause haze and ozone (O3). The adsorption technique is one of the efficient and simple methods to remove VOCs, but the presence of water vapor can compete with VOCs in the practical applications. It is of great significance to design hydrophobic adsorbents with high VOCs adsorption performance. Recently, focusing on the surface hydrophilicity of zeolites and the problems that exist in the application of VOCs adsorption under humid conditions, the "Air Pollution Control and Biomass Energy Laboratory" (http://catalysis.tju.edu.cn/), from the School of Environmental Science and Engineering made use ofthe hydrophobicity of porous organic polymers, designed and synthesized a series of zeolites and porous organic polymer core-shell structure adsorbents.
The developed adsorbents effectively improved the hydrophobicity of the zeolites and greatly improved their toluene adsorption performance under dry and humid conditions. Relevant research result "Core-shell structured Y zeolite/hydrophobic organic polymer with improved toluene adsorption capacity under dry and wet conditions" has been published in Chemical Engineering Journal (IF: 10.652), an international high-level environmental journal.This work not only proposes a new hydrophobic zeolite-based VOCs adsorbent, but also provides a new idea for the preparation of a series of hydrophobic adsorbents.
