Preparation method and application of titanium-containing silicon oxide material with high thermal stability

The invention relates to a preparation method and application of a titanium-containing silicon oxide material with high thermal stability. An aqueous solution prepared from a titanium source, a silicon source, an alkali source, a template molecule and a peroxide is subjected to solid-liquid separation after being stirred, dried and then subjected to a simple calcination process to obtain the titanium-containing silicon oxide material having a high specific surface area. Since the titanium-containing silicon oxide material prepared by the method has high thermal stability, the material still has excellent catalytic activity after calcination and can be used for catalyzing olefinic compounds to conduct an epoxidation reaction, and production of epoxides is facilitated. 本发明涉及种具有高热稳定性的含钛氧化硅材料的制备方法及应用，是将由钛源、硅源、碱源、模板分子以及过氧化物所配制的水溶液，经搅拌后进行固液分离并干燥，接着，经过简单的煅烧程序即可得到具有高比表面积的含钛氧化硅材料；由于本发明所制备的含钛氧化硅材料具有较高的热稳定性，因此在经过煅烧后仍具有杰出的催化活性，可用来催化烯烃类化合物进行环氧化反应，有助于环氧化物的生产。
