小角X射线散射在分子筛研究中的应用
Review on application of small angle X-ray scattering to synthesis and characterization of zeolite
摘要
Abstract
As a physical technique, small angle X-ray scatter (SAXS) can be used to study the geometric structure of inhomogeneous electron density zone inside the matter at nanometer level. This review focuses on advantages and features of synchrotron radiation X-ray source SAXS, and the newly progress of its application to characterizations of sol-gel process, synthesis process and structure of zeolite, in particular, the existence behavior of silicoaluminum species in sol-gel system, the influence on synthesis of zeolite and the fractal structure, particle size, mesoporous size, morphology and interface features of zeolite. Finally, the problems existing in SAXS application to zeolite-related researches are discussed and the future research direction is proposed.关键词
