摘要
综述了各类纤维素复合催化剂在污水降解处理领域的应用进展。重点介绍了天然植物纤维基复合催化剂、细菌纤维素基复合催化剂、纤维素纳米纤维基复合催化剂和纤维素衍生材料复合催化剂,总结了它们作为基底材料的优缺点,并简要分析了其制备工艺、催化性能及作用机理。指出纤维素及其衍生物作为复合催化剂的基底材料,不仅具有分散和固定作用,还能吸附水体中的有机污染物,增加催化剂与污染物的接触。最后,对目前纤维素复合催化剂的研究工作进行归纳总结,并展望了未来的发展方向,为纤维素复合催化剂在污水降解领域的深入研究提供了思路与参考。
This paper reviews the progress of the application of various types of cellulose-based composite catalysts in the field of degradation and treatment of pollutants in wastewater,focusing on natural plant fiber-based composite catalysts,bacterial cellulose-based composite catalysts,cellulose nanofiber-based composite catalysts,and cellulose-derived material composite catalysts.The advantages and disadvantages of their use as substrate materials are summarized.The preparation process,catalytic performance,and mechanism of action are briefly analyzed.It is pointed out that cellulose and its derivatives,as the substrate materials of composite catalysts,not only have the dispersing and immobilizing effects,but also can adsorb the organic pollutants in the water and increased exposure of catalysts to contaminants.Finally,the current research progress on cellulose-based composite catalysts is summarized and the future development direction is envisioned,which provides ideas and references for the in-depth research of cellulose-based composite catalysts in the field of degradation.
