Influe nce of sodium dod ecyl sulf ate micelles on the Palladium Nanoparticle fo rmation on GNS f or oxygen reduction reacti on

Graphene (G) is a two-dim ensional single-layer sheet of g raphite with p-electrons fully delocalized on the graphitic plane. It is highly conductive and mechanically strong and has been found for molecular electronic device, energy storage, fuel cell and catalytic applications. It has been sho wn in the Pt (or Pd)-based nanopa rticle (NP) catalysts grown on G for electrocatalytic reactions and in the activation of Co۳O۴ and MoS۲ NPs by G for oxygen reducti on reaction (ORR) in alkaline me dia and for hydrogen e volution in H۲SO۴ solution. In these studies, the catalyst N Ps were grown directly on the G surface to maximiz e GíNP contact and to achieve the des ired catalysis enhancement. The objective of our work is to use the elec trodeposition method to disperse small palladium partic les on grap hene sheets, which was previously electrosynthesised on a glassy carbon electrode from an aqueo us acid solutio n[۱-۳].
