Title: Size and shape of rhenium nanoparticles.

Abstract

In this paper the results from a detailed XAFS characterization of supported rhenium nanoparticles are presented. The Re nanoparticles are formed by the reduction of dispersed supported rhenium oxide in the presence of moist hydrogen. The shape of the wet-reduced Re clusters is determined by comparing the EXAFS spectra of Re-metal to the Re-wet-reduced clusters to 6 {angstrom}. A decrease in the signal from the 4th and 7th Re shells is an indication of sheet-like rather than spherical-like particles.
