摘    要:以十二烷基硫酸钠(DDS)、十六烷基三甲基溴化铵(CTAB)、聚丙烯-聚乙烯-聚丙烯三嵌段共聚物(P123)为模板剂,以硫酸钛和偏硅酸钠为金属源,使用三模板剂法首次合成出钛硅介孔纳米球材料。用XRD,ICP,HRTEM,SEM,FTIR和低温氮吸附等多种手段对材料进行了表征。结果表明,所制备的钛-硅材料是介孔纳米球结构,球径约为2 000 nm。当n(钛)/n(硅)增加时,介孔孔径增大,比表面积降低。

关 键 词:三模板剂  钛-硅  介孔  纳米球

Abstract:Mesoporous titanium-silica nanosphere was synthesized by tri-surfactant method,using dodecyl sodium sulfate(DDS),Cetyltrimethylammonium bromide(CTAB),Poly(propylene glycol)-block-poly(ethylene glycol)-poly(propylene glycol)(P123) as surfactant and titanium sulfate,sodium silicate as metal source.The material was characterized by XRD,nitrogen adsorption/desorption,ICP,HRTEM,SEM and FTIR.The results indicate that the synthesized sample is mesoporous nanosphere material,diameter of the sphere is about 2 000 nm...
Keywords:tri-surfactant  titanium-silica  mesoporous  nanosphere
