摘要/Abstract

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.

关键词: 介孔TiO₂, 氯化十六烷基吡啶, 模板剂

Abstract: 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 were studied. The samples were characterized by FT-IR, TG-DTA, XRD, and N₂ adsorption techniques respectively. The results show that specific surface and thermal stabability are improved by using mesitylene and phosphoric acid. At the same time, it can exhibit the better photoreactivity.

Key words: mesoporous TiO₂, n-cetylpyridinium chloride, characteristics, template
