MOFs基多孔材料吸附去除VOCs的研究进展

大气中挥发性有机物（VOCs）严重威胁生态环境和人类健康，其治理迫在眉睫。吸附法因操作简单、效率高、能耗低等优势成为目前处理VOCs最经济有效的方法之一。但传统吸附材料如分子筛、活性炭、硅藻土等存在吸附容量小、易堵塞、选择性低且再生困难等问题。因此，发展高效稳定的VOCs吸附材料仍是目前的研究热点。金属有机框架材料（metal-organic frameworks，MOFs）是一种比表面积高、孔道结构丰富的新型多孔材料，在VOCs吸附净化方面具有良好的应用潜力。针对近10年MOFs基多孔材料吸附去除VOCs的研究，从MOFs的结构和特点出发，详述MOFs的分类及其复合材料的类型，基于MOFs基多孔材料吸附VOCs过程中的影响因素和机制，对其在VOCs吸附应用方面的研究进展进行总结，并对其在该领域的未来发展进行展望。

RESEARCH PROGRESS OF MOFs-BASED POROUS MATERIALS IN ADSORPTIVE REMOVAL OF VOCs

Volatile organic compounds (VOCs) in the atmosphere are harmful to the ecological environment and human health, and need urgent treatment. The adsorption method has become one of the most economical and effective methods for VOCs removal, due to its advantages of simple operation, high efficiency, and low energy consumption. Traditional adsorption materials such as molecular sieve, activated carbon, and diatomite are limited by small adsorption capacity, easy plugging, low selectivity, difficult regeneration, etc. Therefore, it is still a current research hotspot to develop efficient and stable VOCs adsorption materials. Metal-organic frameworks (MOFs), as a new type of porous material, have shown good performance in VOCs adsorption due to their high specific surface area, abundant pore structures, and adjustable chemical characters. This review focused on the studies of VOCs adsorption using MOFs-based porous materials in the past 10 years. Starting from the structures and characteristics of MOFs, the classification of MOFs and types of their composites were described in detail. Based on the influential factors and adsorption mechanisms in the adsorption process of VOCs on MOFs-based porous materials, the research progress of MOFs-based porous materials in the application of VOCs adsorption was summarized and its future development in this field was looked forward.
