摘要
以氯化十六烷基吡啶为模板剂,在室温下直接合成出介孔TiO2,探讨了合成条件的影响,分别用红外光谱(FT IR)、热分析(TG DTA),X射线粉末衍射(XRD)和N2吸附等温线技术对产物进行了表征.结果表明:样品经均三甲苯和磷酸处理后能有效提高比表面积和热稳定性,具有较高的光催化活性.
Using n-cetylpyridinium chloride as template, mesoporous TiO2 was prepared by direct synthesis at room temperature. At the same time, the effect of synthesized conditions on samples was studied. The samples were characterized by FT-IR, TG-DTA, XRD, and N2 adsorption techniques respectively. The results show that specific surface and thermal stability are improved by using mesitylene and phosphoric acid. At the same time, it can exhibit the better photoreactivity.
