Abstract

To meet the growing emission of water contaminants, the development of new materials that enhance the efficiency of the water treatment system is urgent. Ordered mesoporous materials provide opportunities in environmental processing applications due to their exceptionally high surface areas, large pore sizes, and enough pore volumes. These properties might enhance the performance of materials concerning adsorption/catalysis capability, durability, and stability. In this review, we enumerate the ordered mesoporous materials as adsorbents/catalysts and their modifications in water pollution treatment from the past decade, including heavy metals (Hg2+, Pb2+, Cd2+, Cr6+, etc.), toxic anions (nitrate, phosphate, fluoride, etc.), and organic contaminants (organic dyes, antibiotics, etc.). These contributions demonstrate a deep understanding of the synergistic effect between the incorporated framework and homogeneous active centers. Besides, the challenges and perspectives of the future developments of ordered mesoporous materials in wastewater treatment are proposed. This work provides a theoretical basis and complete summary for the application of ordered mesoporous materials in the removal of contaminants from aqueous solutions.

用于水污染处理的有序介孔材料:吸附和催化

为了满足日益增长的水污染物排放，开发提高水处理系统效率的新材料迫在眉睫。有序介孔材料由于其高表面积、大孔径和足够的孔体积，为环境处理应用提供了机会。这些特性可能会提高材料的吸附/催化能力、耐久性和稳定性。本文综述了近十年来作为吸附剂/催化剂的有序介孔材料及其改性在水污染处理中的应用，包括重金属(Hg2+、Pb2+、Cd2+、Cr6+等)、有毒阴离子(硝酸盐、磷酸盐、氟化物等)和有机污染物(有机染料、抗生素等)。这些贡献表明了对合并框架和均质活性中心之间的协同效应的深刻理解。最后，对有序介孔材料在污水处理中的应用前景进行了展望。本研究为有序介孔材料在去除水中污染物方面的应用提供了理论基础和完整的总结。
