Abstract

Catalytic reactions of Rh/graphite nanofiber samples treated in H 2 were studied using electron microscopy. Several small Rh particles were observed behind each other, partly overlaid by the graphite lattice structure. The diffuse and amorphous overlayer on both graphite and Rh particles could correspond to oxidized species on a sample kept in air before carrying out the TEM examinations. The X-ray photoelectron spectroscopy (XPS) analysis showed up to 5% oxygen and about a half of Rh to be present as Rh 2O3 in an untreated sample.
