Summary:Mass-depending morphologies of nanostructured Palladium obtained via the carbonyl chemical route. [Display omitted] •Mass-depending morphology was observed in nanostructured palladium supported on carbon prepared by the carbonyl chemical route.•The Morphological effect of carbon supported Pd was investigated towards ORR. Carbon supported palladium nanostructures were synthesized via the carbonyl chemical route. Compared with nanostructured platinum, prepared via carbonyl chemical route, Pd nanomaterials showed mass-loading morphology, whereas particle size and morphology of Pt nanostructures was constant. The oxygen reduction reaction (ORR) on nanostructured Pd, with different morphology in both acid and alkaline medium was investigated. A relationship, based on X-ray diffraction structural analysis pattern, transmission electron microscope, with the Pd morphological effect on ORR activity was identified.
