Abstract

Abstract: Highly ordered cubic Zr-doped mesoporous silica was directly prepared with Evaporation-Induced Self Assembly method(EISA) with triblock copolymers(Pluronic P123) as the structure-directing agents. The mesoporous material was characterized via small-angle powder X-ray diffraction(XRD), transmission electron microscopy(TEM), and nitrogen adsorption. The results show that the product has a face-centered cubic structure with space group of Fd3m. N₂ sorption revealed that the Zr-doped mesoporous silica has not only ordered structures, but also high surface area(550 m²/g), large pore volume(0.66 cm³/g), as well as uniform pore size(4.0 nm).

Key words: Mesoporous silica, Zirconia, Cubic phase, Evaporation-induced self-assembly(EISA)
