摘要
采用水热晶化法首次合成出具有MCM-41型结构的中孔(Mesopore)杂原子SnMCM-41分子筛.XRD、骨架IR、紫外漫反射、固体魔角核磁等测试结果表明,锡原子处于分子筛骨架上.苯酚羟基化反应显示,SnMCM-41具有一定的选择催化氧化性能.
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.
