采用X射线衍射技术(XRD)考察了金属氧化物V2O5在介孔二氧化硅分子筛上的分散,研究结果表明应用浸渍法将V2O5浸渍于介孔二氧化硅分子筛中,在低于V2O5熔点的适当温度下焙烧后,与未浸渍V2O5样品相比,晶胞参数a值明显增大,说明钒离子掺入了介孔二氧化硅分子筛的骨架中;在一定范围内随着V2O5加入量的增加其在介孔二氧化硅的表面的分散量也在增加,而V2O5残余晶相量远远低于加入的量,说明V2O5掺入介孔二氧化硅分子筛骨架的同时可在介孔二氧化硅的表面成单层分散。

补充资料：浸渍法
分子式：
CAS号：
性质：制造固体催化剂的方法之一，即将一种或几种活性组分通过浸渍载体负载在载体上的方法。通常是用载体与金属盐类的水溶液接触，使金属盐类溶液吸附或贮存在载体毛细管中，除去过剩的溶液，再经干燥、煅烧和活化制得催化剂。浸渍方式有过量溶液浸泡与等体积吸附等。有时加入竞争吸附剂使活性组分均匀吸附在整个载体上。铂重整催化剂是用氯铂酸水溶液浸渍η-Al2O3制得。浸渍法比较经济，且催化剂形状、表面积、孔隙率等主要取决于载体，容易选取。
