Electro-catalyst, Oxygen reduction reaction, Graphene, Palladium nanoparticles

The oxygen reduction reaction (ORR) on Pd nanoparticles decorated chlorine doped reducedgraphene oxide (Pd/Cl-RGO) electrocatalyst have been investigated in alkaline media. Pd is apromising alternative to the expensive platinum. The surface morphology of prepared materials(RGO, Cl-RGO and Pd/Cl-RGO) is studied by transmission electron microscopy (TEM). Thecharacterization of synthesis catalysts was performed by FT-IR, XRD and Raman techniques.The electrocatalyst performances are investigated by cyclic voltammetry, linear sweepvoltammetry, and electrochemical impedance spectroscopy in 0.1 M KOH
