The textural and structural properties were characterized by X-ray diffraction, nitrogen adsorption analysis, and transmission electron microscope. Comparison between pure mesoporous silica and mesoporous silica-zirconia nanocomposite was also presented in this work. The surface area, pore size, and pore volume decreased as the Zr doping in the mesoporous silica framework. But the obtained nanocomposite maintained the cubic Im3m-type mesoporous structure.展开更多
