含钨介孔SiO_2的合成、表征及其催化性能

Synthesis,Characterization and Catalytic Properties of Tungsten-containing Mesoporous Silica

分别以廉价硅酸钠与正硅酸乙酯为硅源,通过复合模板剂制备了介孔二氧化硅,并利用吸附相反应技术合成了WO3/SiO2复合催化剂。用XRD,TEM等手段对其结构进行了表征,通过油酸的催化氧化反应考察了催化剂的催化性能。

Mesoporous silicas were synthesized with sodium silicate or TEOS as silica source,TritonX-100 and CTAB as composite template.The WO3/SiO2 composite catalysts were prepared by adsorption phase reaction technique.The structures of SiO2 and WO3/SiO2 were characterized by XRD and TEM,and the catalytic properties were tested by catalytic oxidation of oleic acid.
