Keywords: 介孔二氧化钛,水热合成,结构表征,光催化活性,2,4,6-三溴苯酚
Abstract:
？以聚丙二醇(PPG)为模板剂,采用水热法制备了可控介孔TiO2纳米晶体.醋酸水溶液为水解抑制剂和催化剂.运用X射线衍射、热重分析、扫描电镜和氮气吸附-脱附等技术对样品进行了表征.详细考察了制备过程、模板剂含量和煅烧温度等参数对样品结构和光催化活性的影响,并将样品用于紫外光下降解水体中典型溴代阻燃剂2,4,6-三溴苯酚的反应中,阐明制备的介孔TiO2结构与光催化活性之间的关系.结果表明,所制样品为具有规则孔道结构、较大的孔径和较高比表面积的介孔TiO2.其中,在400°C煅烧、PPG添加量为20%时所得介孔TiO2的光催化活性最高,反应1h可将100umol/L的2,4,6-三溴苯酚完全降解.
