EU-1high-silica zeoliteframework topologycrystal structureRietveld refinementWe propose a model for the framework topology of the novel zeolite EU-1. This is based on electron diffraction, model building, subsequent DLS refinement, and a limited Rietveld refinement of the X-ray powder diffraction ...

The first organically templated 3D borogermanate with a novel zeolite-type topology, (C4N3H15)[(BO2)2(GeO2)4] FJ-17, has been solvothermally synthesized and characterized by IR spectroscopy, powder X-ray diffraction (PXRD), TGA, and single-crystal X-ray diffraction. The compound crystallized ...
Zeolite RHO has an unusual three-dimensional monolayer surface with a topology that gives equal access to either side of the surface. In the absence of supporting structural subunits, e.g., smaller cages or channels, RHO exhibits atypical framework flexibility with large displacive rearrangements. ...
A microporous aluminogermanate possessing zeolite rho framework topology has been synthesized from sodium and cesium containing gel mixtures. The dehydrated material of composition Na16Cs8Al24Ge24O96 has been structurally characterized via combined Rietveld analysis of synchrotron X-ray and neutron diffract...

Thomas Vogt3 & Yongjae Lee1 Systematic studies of pressure-induced amorphization of natrolites (PIA) containing monovalent extra-framework cations (EFC) Li+, Na+, K+, Rb+, Cs+ allow us to assess the role of two different EFC-H2O configurations within the pores of a zeolite: one arran...
However, in the case of MIL-100(Fe), the degradation of the framework seems to be affected by the nature of the contaminant, being favored in the presence of At. The amide of At may preferentially interact with the Fe metal sites than with the Ti ones (more oxophilic). Finally, the ...
