文摘Nb\|containing mesoporous MCM\|41 silica molecular sieves were synthesized successfully under acidic condition by using cetylpyridinium bromide (CPBr) as template. The results of characterization by means of XRD, DR UV\|Vis, ICP\|AES, and N 2 adsorption/desorption techniques indicated that Nb is highly dispersed in the MCM\|41 frameworks.
