Performances of a Hybrid Carbon Material Supported Pd Catalyst for Ethanol Electrooxidation†

doi:10.7503/cjcu20170303

Abstract

Abstract:

A novel Pd/C-GNP catalyst was prepared using a hybrid carbon support composed of graphene nanoplatelets(GNP) and carbon black, and the performances of the catalyst for ethanol electrooxidation in alkaline media were evaluated. Transmission electron microscopy(TEM) and X-ray diffraction(XRD) measurements showed that the structure of the catalyst was improved and the dispersion of the Pd nanoparticles was facilitated by using the hybrid carbon support. Electrochemical measurements showed that the Pd/C-GNP catalyst had a high electrochemical active surface area. The ethanol-oxidation activity of Pd/C-GNP was remarkably higher than that of Pd/GNP and Pd/C in alkaline media. In addition, Pd/C-GNP exhibited an improved poison resistance and a high electrochemical stability, which could be attributed to the interaction between Pd nanoparticles and the carbon support.
