Abstract: Mesoporous silica nano-materials (MSNs) have been widely used in various fields, e.g., adsorption, catalysis, and biomedicine, due to their large specific surface area as well as stable physical and chemical properties. In recent years, relevant niches of the academia have been committing themselves to regulating and controlling the morphology and structure of MSNs (particle size, particle shape, channel structure, and readily-functionalized surface), because the fineness of the material's structure has a significant impact on its physical and chemical properties, which will in turn translates to its performance and application. Pure silica materials, however, have their application scopes limited due to their lack of specificity. In this sense, how to improve their specificity and open up more fields of application have become popular research topics. Compared with the conventional two-dimensional mesoporous silica materials, dendritic fibrous nano-silica (DFNS) has a more open and more permeable dendritic pore structure. The modifiable surface and special radial channel structure of the dendritic fibrous nano-silica can combine the excellent physical and chemical properties of the silica nano-material with the modified functional specificity arising from the actual need. This signifies a qualitative leap in the application prospect of the MSNs, allowing more and more applications to gradually emerge across various fields. This paper concludes and reviews the synthesis and morphological regulation of DFNS based on the work of the research team. Furthermore, the applications of functional materials prepared by coating magnetic core-shell structures, grafting functional groups and chemical monomers, or with the use of supported metals or metallic oxides in adsorption, catalysis, biomedicine, chromatographic stationary phase, gas capture and other fields have also been summarized.
