摘要
酚类化合物广泛存在于空气、废水和土壤中,严重危害自然环境和人类健康。加强此类化合物的处理是科研工作者的研究重点。本文总结了树枝状介孔SiO_(2)纳米粒子(dendritic mesoporous silica nanoparticles,DMSNs)对酚类化合物吸附、降解的最新研究进展。重点探讨了DMSNs催化剂的设计思路以及在对硝基苯酚、苯酚、双酚A、邻氯苯酚等多种酚类化合物方面的应用和反应机制,为后续设计出绿色环保、吸附降解性能优异的功能材料提供了理论基础,并且展望了此类催化剂降解酚类污染物的发展方向。
Phenolic compounds are widely existed in air,waste water and soil,which seriously harm the natural environment and human health.Strengthening the treatment of these compounds is the focus of researchers.The latest research progress of dendritic mesoporous silica nanoparticles(DMSNs)on the adsorption and degradation of phenolic compounds was summarized in this paper.The design strategies of catalysts based on DMSNs and the applications and reaction mechanisms of DMSNs in the treatment of phenolic compounds such as p-nitrophenol,phenol,bisphenol A and o-chlorophenol have been emphatically reviewed,which provides a theoretical basis and trends for the design of green functional materials with better adsorption and degradation performance.
