Abstract:
Multiwalled carbon nanotube (MWCNT) supported Pt catalyst nanoparticles were successfully prepared by using improved aqueous impregnation method. Catalyst nanoparticles were characterized by HR-TEM and XRD measurements. According to the results of physicochemical characterizations external surface of the MWCNTs were decorated by the uniform arrangement of the Pt nanoparticles with fcc crystalline structure. Results of the electrochemicalcharacterization of the catalysts revealed that the prepared catalyst exhibit enhanced electrocatalytic performance. It is believed that high electrochemical activity of the prepared catalyst is mostly due to high utilization of catalyst particles and good physical properties of MWCNT supporting material
