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.

以P123为模板剂,正硅酸乙酯为硅源,氯化氧锆和硝酸亚铈为无机前驱盐,在不外加无机酸的条件下,利用无机前驱盐自身水解产生的弱酸性环境,通过水热合成路线一步合成了具有大的径轴比、短孔道、六方板状形貌的Zr-Ce-SBA-15介孔材料。

But who-and-ink color reproduction system using organic and inorganic does not equal amounts, the contrasting color content, compared to when there are changes to the strong will to change, when in case of acids and bases are often transient, as time went on, the juxtapositional will be deep color ink to dark or lighter, faded and Matt.
