Microporous and mesoporous minerals are key elements of advanced technological cycles nowadays. Nature-driven microporous materials are known for biocompatibility and renewability. Zeolite is known as an eminent microporous hydrated aluminosilicate mineral containing alkali metals. It is commercially available as adsorbent and catalyst. However, the large quantity of water uptake occupies active sites of zeolite making it less efficient. The widely-used chitosan polysaccharide has also been used in miscellaneous applications, particularly in medicine. However, inferior mechanical properties hampered its usage. Chitosan-modified zeolite composites exhibit superior properties compared to parent materials for innumerable requests. The alliance between a microporous and a biocompatible material with the accompaniment of negative and positive charges, micro/nanopores and proper mechanical properties proposes promising platforms for different uses. In this review, chitosan-modified zeolite composites and their applications have been overviewed.
微孔和介孔矿物是当今先进技术循环的关键要素。受自然启发的微孔材料以生物相容性和可再生性而闻名。沸石是一种含碱金属的著名微孔水合铝硅酸盐矿物。它可作为商业吸附剂和催化剂使用。然而，大量的吸水会占据沸石的活性位，从而降低其效率。广泛使用的壳聚糖多糖也已在各种应用中使用，特别是在医学中。然而，较差的机械性能阻碍了它的使用。与母体材料相比，壳聚糖改性沸石复合材料在无数需求下表现出更好的性能。微孔和亲生物材料与正负电荷、微/纳米孔和适当的机械性能的结合，为各种用途提供了有前景的平台。在这篇综述中，概述了壳聚糖改性沸石复合材料及其应用。
