摘要: X射线衍射、红外光谱、X射线光电子能谱、磁化率、电子自旋共振等研究结果表明, 杂原子以畸变四面体配位方式占据M-ZSM-48(M=B、Cr、Ge、V)型分子筛骨架, V、Cr分别以V(Ⅳ)和Cr(Ⅲ)形式存在。

Abstract: It was identified by many techniques such as XRD, IR, XPS, ESR and magnetic susceptibility measurement that the hetero-atoms on the frameworks of M-ZSM-48 type molecular sieves reside at the sites of distorted tetrahedral coordination. V and Cr exist as V(Ⅳ) and Cr(Ⅲ) respectively.
