核壳结构beta/mcm-22双微孔复合分子筛的合成与表征
, PP. 1240-1245
Keywords: beta,mcm-22,核壳结构,复合分子筛,等离子体
Abstract:
？以beta分子筛为晶核,通过二步水热晶化法成功制备了形态良好的beta/mcm-22核壳结构复合分子筛。采用x射线衍射(xrd)、扫描电镜(sem)、透射电镜(tem)及n2吸附-脱附技术等对分子筛进行了表征。结果表明,复合分子筛形态规整,beta与mcm-22分别作为核壳而共生;beta/mcm-22复合分子筛孔结构性质介于mcm-22、beta分子筛之间。在酸性分布上,复合分子筛的中强酸及b酸所占比例显著增加(cb/cl=13.8)。通过ar-h2等离子体对beta分子筛进行处理,使其表面能提高并使表面正电荷富集、硅羟基增加,这是形成良好beta/mcm-22核壳结构的内在原因。
