摘要：
Volatile organic compounds (VOCs) emission has caused serious atmospheric environment pollution in China. As the industrial VOCs emission has the characteristics of low concentration, large air volume, and water containing, the adsorption treatment with molecular sieve becomes very important. The factors affecting molecular sieve adsorption of VOCs are the pore structure, surface properties, hydrophobicity and so on. The results show that the adsorption performance of the molecular sieves with the pore size matching the kinetic size of the adsorbate and hierarchical structure is good, and the introduction of appropriate compensating cation can also enhance the adsorption. The mainstream of current development includes to increase the silicon to aluminum ratio, to improve the hydrophobicity of molecular sieve by silanization modification, to avoid using template agent, and to reduce costs and pollution. It has become a new topic to realize green synthesis to reduce the energy consumption by replacing the traditional hydrothermal synthesis method by solid phase method, microwave assistance and seed introduction. Research and development of multi-functional integrated materials and combination of adsorption with other methods to deal with VOCs has become the future trend. © 2022, Editorial Board of CIESC Journal.
