Highly ordered mesoporous Zr-Ce-SBA-15 silica with hexagonal-platelet morphology was synthesized through a hydrothermal route by using pluronic P123 as a template, tetraethyl orthosilicate as a silica source, zirconyl chloride and cerous nitrate as a precursor. The main strategy of this method was to utilize the acidity self-generated from the hydrolysis of inorganic salts in the aqueous solutions, where no addition of mineral acids was necessary.
