The mesoporous silicas were impregnated by vion solution and calcined in air at 400 °C,the investigation indicated not only vanadium in samples prepared by impregnation method was incorporated into the famework of mesoporous silicas,but also some dispersed spontaneously onto the surface of mesoporous silicas,and formed a monolayer if total amount of V2O5 increased.
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。

分子式：
CAS号：
性质：采用熔融金属、液态润滑剂或其他液态非金属物质来浸渍多孔骨架状固体的方法。该法基于毛细管渗透原理。可分为全浸法，部分浸入法，表面接触法等。还可采用液压，离心力，抽真空等措施增加渗透的附加压力。这种工艺已被广泛应用于许多领域。如多晶氧化铝自润滑含油轴承(将烧好的多晶轴承浸入油中)、金属陶瓷无油润滑活塞环(金属陶瓷浸渍于液态塑料中)、钨渗铜的喷管材料、用熔融的镍、钴、铁浸渍的钨与碳化钛工具和模具材料等。
