Research Progress of Dendritic Fibrous Nano-silica (DFNS)

doi:10.15541/jim20180247

Abstract

Abstract:

Dendritic fibrous nano-silica (DFNS), especially the sphere-shaped with three-dimensional (3D) center- radial channels and hierarchical pores, possess higher specific surface areas, larger pore volumes, higher pore permeability, more accessible internal spaces, etc. Guest substances (e.g., ultrasmall nanoparticles) can be loaded onto and transported in the radial nanochannels, or can even react with the chemically active sites in these nanochannels. As a result, DFNS can serve as promising platforms to construct novel nanocatalysts, adsorbent materials, and delivery systems for genes, proteins or drugs. A majority of investigations about DFNS have demonstrated that silica nanospheres with this special topography have inherent superiorities over traditional mesoporous MCM-41 or SBA-15, and can be perfect alternatives. Nevertheless, reviews on DFNS are limited, and there still exist plenty of issues that need to be probed into. Therefore, this comprehensive review provides a critical survey on DFNS’ structural characteristics, commonly used structural models, novel structures, real-time applications, etc. We sincerely expect that this paper could give material scientists and chemists certain inspiration to accelerate DFNS family’s booming evolution.

Key words: dendritic fibrous, silica, structural models, novel structures, real-time applications
