Long-Term Activity of Pd-Co/rGO Nano-Catalyst in Ethylene Glycol Electro-oxidation Reaction in Alkaline Media

The Pd-Co/rGO nano-catalysts were used as electro-catalysts for the ethylene glycol (EG) oxidation reaction in alkaline media. The long-term activity of Pd-Co/rGO was investigated in the Half-cell by electrochemical techniques such as cyclic voltammetry (CV) and chronoamperometry (CA) techniques. CV results of EG electro-oxidation reaction on the Pd-Co/rGO were compared to the reported results in the literature. Eonset and Sap were -0.3 V and 450 (mA/ mgPd) , respectively, suggesting an excellent activity of Pd-Co/rGO in EG oxidation reaction in alkaline media. The low long term poisoning rate (0.018) of Pd-Co/rGO resulted from CA test determines high long-term activity and stability of Pd-Co/rGO in EG electro-oxidation reaction.
