Abstract

A novel five-step method for fabricating mesoporous SiO2 glass was described in this paper, which consists of: (1) formation of colloidal suspension of Zn(OH)2, (2) synthesis of silica sol, (3) mixture of Zn(OH)2 colloidal suspension and silica sol to form nano-ZnO embedded precursor glass, (4) annealing of the precursor glass, and (5) treating nano-ZnO embedded glass with HCl to obtain the mesoporous glass. The mesostructure of the glass was investigated by X-ray diffraction (XRD), field emission scanning electron microscope (SEM), and BET surface area analysis. The average pore size distribution is in the range of 3.7 nm, and the surface area is as high as 496.5 m2/g.
