Controlled synthesis of mesoporous NbMSU-X: influence of the preparation route
Mesoporous NbMSU-X has been successfully prepared for the first time by using tetraethyl orthosilicate, ammonium tris(oxalate) complex of niobium(V) and fatty alcohol polyoxyethylenepolyoxypropylene ether as the source of silicone, niobium and mesostructuredirecting agent, respectively and by variation of the pH value of the synthesis gel. The Nb-MSU materials were characterized by XRD, TEM, N2 adsorption-desorption, FTIR and DRUV-Vis techniques. The TEM images confirmed that NbMSU took on worm-like mesostructure similar to MSU-1. The influence of the synthesis conditions on the niobosilicate porous structure has been analyzed.
