Nanostructured rhenium dioxide: Synthesis and characterization

Nanostructured rhenium oxides, which belong to the technically important gr oup 7 transition metal oxides, have been inaccessible until now due to the lack of appropriate precursors and reaction templates. Using methyltrioxorh enium as the organometallic rhenium precursor and long-chain alkylamines as supramolecular templates, these authors have synthesized nanostructured rh enium dioxide for the first time. The products are nanocomposites that are composed of rhenium dioxide and the organic structure-directing agent used in the preparation.
