  • The generous financial assistance of the Natural Sciences and Engineering Research Council of Canada's operating: grant program is deeply appreciated. AM is grateful to NSERC for a graduate scholarship held during the tenure of this work. The low temperature EXAFS measurement were carried out at the National Synchrotron Light Source, Brookhaven National Laboratories, which is supported by the US Department of Energy, Division of Materials Sciences and the Division of Chemical Sciences. The assistance of Dr. Alex Kuperman with the collection of the XPS data proved to be most useful. Finally the authors would like to acknowledge initial discussions with Prof. Wolfgang A. Herrmann regarding this study.

Abstract

Zeolite-encapsulated molecular forms of rhenium oxide offer the opportunity to tune the physico-chemical properties of the materials due to the wide range of oxidation states available to rhenium (+7–1) This can lead to nanomaterials with interesting electronic, optical, and catalytic properties. Here, the encapslation, structural characterization, thermal and chemical stability of CH3ReO3 in both sodium and acid forms of zeolite Y are reported.
