As industrial wastewater pollutants,dyes have caused serious harm to human health and the ecological environment.It is of great significance to remove dyes and their derivatives from wastewater efficiently and environmentally.With the characteristics of central radial channels,a large specific surface area and high porosity,dendritic mesoporous silica nanoparticles(DMSNs)are favored in the field of dye treatment.This article summarizes the latest progress in the adsorption and degradation of dyes by DMSNs.The dyes involved mainly include methylene blue,methyl orange,congo red,malachite green,etc.The preparation methods of DMSNs-based adsorbents and their adsorption and degradation efficiency for dyes are summarized in detail,which provides a reference for subsequent related research.Finally,the development trend of DMSNs-based functional material treatment dyes is summarized and prospected.
