Fabrication of nanocomposite networks using Pd nanoparticles/Polydiphenylamine anchored on the surface of reduced graphene oxide: An efficient anode electrocatalyst for oxidation of methanol
Direct methanol fuel cells (DMFCs) are an essential aspect of electricity and fuel concerns. Herein, we report a new combination of Palladium nanoparticles anchored on polydiphenylamine with reduced graphene oxide network (rGO/PDPA/Pd) nanohybrid synthesized via an in-situ chemical strategy. The rGO/PDPA/Pd electrocatalyst shows excellent electrocatalytic activity, lower oxidation potential (−0.1 V), improved current density (2.85 mA/cm2), excellent cyclic stability (94%), and longevity (1200 s) towards methanol oxidation reaction (MOR) in the alkaline medium, when compared to commercial Pd/C electrocatalyst. Significantly, the forward oxidation peak potential of rGO/PDPA/Pd electrocatalyst was shifted negatively by 110 mV as compared to commercial Pd/C electrocatalyst. These results suggest that rGO/PDPA/Pd electrocatalyst is considered as an effective anode catalyst for DMFCs.
