Abstract

Abstract: An interesting radiolarian-like silica spherulite was prepared from a water-diethyl ether binary solvent system, which is characterized by SEM, TEM, XRD, and adsorption experiments. The results indicate that the silica have a particular morphology and hierarchical structure, i.e., hollow interior and a crust wherein two types of mesopores with radiate orientation are located. This silica product embodies a novel morphosynthesis involving unstable water-oil interface.

Key words: Mesoporous silica, Radiolarian-like shape, Surfactant, Pore structure
