摘要
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).
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 m^2/g） , large pore volume（0.66 cm^3/g） , as well as uniform pore size （4.0 nm）.
