The Nature of the Iron Oxide-Based Catalyst for Dehydrogenation of Ethylbenzene to Styrene. Part 1. Solid-State Chemistry and Bulk Characterization -(the active phase of the catalyst consists of a thin layer of KFeO2 supported on a solid solution of K2Fe22O34 in Fe3O4 (continuous solid-state transformations due to the migration of K+ ions)). -(MUHLER, M.; SCHUETZE, J.; WESEMANN, M.; RAYMENT, T.; DENT, A.; SCHLOEGL, R.; ERTL, G.; J.

structure structure (solids and liquids) D 2000 29 -022 A New Unifying Structural Model of Heteropolymolybdate Salts: Microstructure and Thermal Stability of a Series of Molecular Oxides. -Heteropolymolybdate salts of composition CsxH 4−x PVMo 11 O 40 ·nH 2 O (0 ≤ x ≤ 4) precipitate from aqueous solutions of Cs 2 CO 3 and H 4 PVMo 11 O 40 . The Cs salts (2 ≤ x ≤ 4) have a simple cubic structure, space group Pn3m, as determined by powder XRD. The free acid exhibits a triclinic lattice (space group P-1) for the majority of all crystals and a simple cubic lattice (Pn3m) for a minor fraction of thin crystals. Computer simulation of the XRD pattern suggest that the structure of Cs 2 H 2 PVMo 11 O 40 ·5H 2 O contains defects in the cation lattice. -(BERNDT, S.; HEREIN, D.; ZEMLIN, F.; BECKMANN, E.; WEINBERG, G.; SCHUETZE, J.; MESTL, G.; SCHLOEGL, R.; Ber.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
