Effect of treatment at high temperatures on morphology of a carbon supported Pd catalyst investigated by X-ray diffraction and photoelectron spectroscopy aided with QUASES

摘要

The 20wt% Pd supported on carbon Vulcan XC-72 (Pd/C) anode catalyst, used to formic acid (FA) electro-oxidation reaction, submitted to different high temperature treatment (HTT) procedures in the temperature range 200-400 degrees C was studied using X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) aided with Quantitative Analysis of Surfaces by Electron Spectroscopy (QUASES).
