Abstract
|
In this study, graphene oxide/molybdenum disulfide (GO/MOS2) nanocomposite was prepared using in-situ polymerization method. Next the platinum-nickel (Pt-Ni) was electrochemically decorated on GO/MOS2 nanocomposite surface. Cyclic voltammetry (CV) was employed to evaluate the oxidation of ethanol. Results showed that Pt-Ni/GO/MOS2 exhibits improved electrocatalytic activity ethanol oxidation. Enhanced active surface area of the Pt-Ni/GO/MOS2 electrode (225 mA/cm2) contributes to increase in current density values in the ethanol oxidation as compared to Pt-Pd electrocatalyst.
