摘要: Palladium nanoparticles supported on carbon Vulcan XC72 (Pd/C) and on phosphorus-doped carbon (Pd/PC) were prepared by an alcohol reduction process. X-ray diffractograms of Pd/C and Pd/PC showed the typical face-centered cubic (fcc) structure of Pd. The crystallite sizes of Pd fcc phase were around 8 nm for both samples. X-ray photoelectron spectroscopy revealed to Pd/C and Pd/PC that Pd was found predominantly in the metallic state and to Pd/PC, the presence of P increases the amount of oxygen on the electrocatalyst …
