Preparation method of mesoporous hollow silicon dioxide microsphere

The invention provides a preparation method of a mesoporous hollow silicon dioxide microsphere. The method comprises the following steps: mixing double rosinyl biquaternary ammonium salt, a solvent and ammonia water, so as to obtain an alkaline double rosinyl biquaternary ammonium salt solution; ensuring that the solvent is an ethanol aqueous solution; mixing the alkaline double rosinyl biquaternary ammonium salt solution and ethyl orthosilicate, and then performing hydrothermal reaction, so as to obtain a mesoporous hollow silicon dioxide microsphere precursor; calcining the mesoporous hollowsilicon dioxide microsphere precursor, so as to obtain the mesoporous hollow silicon dioxide microsphere. The preparation method is simple in technology, does not need to use a hard template, and canobtain the mesoporous hollow silicon dioxide microsphere through a soft template only. 本发明提供了种介孔中空二氧化硅微球的制备方法，包括如下步骤：将双松香基双季铵盐、溶剂和氨水混合，得到碱性双松香基双季铵盐溶液；所述溶剂为乙醇水溶液；将所述碱性双松香基双季铵盐溶液与正硅酸乙酯混合后，进行水热反应，得到介孔中空二氧化硅微球前驱体；将所述介孔中空二氧化硅微球前驱体
