摘要: We describe the structural refinement of zeolite beta using local structure obtained with pair distribution function (PDF) method. A high quality synchrotron and two neutron scattering datasets were on samples siliceous beta. The polytypes that make up have same structure; therefore structures was possible experimental PDF. Optimized B used to refine program PDFfit. Refinements only or gave results inconsistent each other but a cyclic good fit both PDFs. show PDF method is viable technique analyze disordered zeolites. However, given complexity most frameworks, use X-ray radiation high-resolution patterns essential obtain reliable refinements.
