| Abstract: | A new tin-containing MCM-41 type mesoporous molecular sieve has been synthe-sized by hydrothermal method. It is confirmed that tin atoms located at framework positionsby means of XRD, framework IR, DRS,29Si MAS NMR techniques. The hydroxylation reac-tions of phenol with aqueous H2O2 indicated that SnMCM-41 is catalytically active. The influ-ence of synthetic factors, thermal stability and adsorption capacity of MCM-41 type molecu-lar sieve have also been elucidated. |
