Structure Analysis in Zeolite Research: From Framework Topologies to Functional Properties

Abstract

The solution and the refi nement of crystal structures of microporous materials are of prime interest for the synthesis and application community in porous solid research. The structure of a material reveals not only the geometry of the bonding network of the rigid framework but also the location of the nonframework constituents responsible for the porosity of the material. Analyzing the structure, therefore, unveils the synthesis protocol including nucleation and growth. The properties related to the porous net correspond to the local structure, i.e., the composition and the geometry of local confi gurations. It thus inspires ideas about possible properties and modifi cations to improve functionality.The chapter is intended to highlight the contribution of crystallographic analysis of microporous materials and in particular porous silicates to the success of this class of materials. It does not survey the continuous growth of materials in the fi eld but show how the insight gained from crystallographic studies acted as catalyst in the further development of the fi eld.
