Support effect on electrocatalytic performance of methanol oxidation over platinum catalysts

Graphene oxide and carbon nanotubes supported Pt nanoparticles were successfully synthesized by wet chemical reduction method. The structures methanol oxidation performance of the two catalysts characterized scanning electron microscope (SEM), transmission (TEM), X-ray diffraction (XRD), Raman spectroscopy (Raman) electrochemical workstation. results show that graphene exhibits higher active surface area, activity stability compared with nanotubes. It is proposed well dispersed on plays an important role for excellent performancefor oxidation.
