A High-Performance Bimetallic Pd-Cu Nanoparticles Membrane on Glassy Carbon Electrode for Formic Acid Oxidation

Abstract:

The Palladium-copper nanoparticles (PdCu NPs) have been prepared by potentiostatic electrodeposition from a mixture electrolyte of H₂PdCl₄and CuSO₄,then placed the electrode in sulfuric acid using cyclic voltammetry sweep a few laps to fabricate the PdCu NPs/glass carbon electrode (Pd-Cu/GCE). The modified electrode electrochemical properties of a preliminary study found that this modified electrode has good stability and electrochemical activity, experiments show that formic aicd has good voltammetric response of the electrode. The electrical activity of the formic acid in the Pd/GCE is lower than that in the Pd-Cu/GCE, this is due to the synergistic effect of the bimetal. When the Cu content is increased gradually in H₂PdCl₄and CuSO₄ a mixed solution, the formic acid oxidation peak currentlower, because Cu has no electrocatalytic activity for formic acid oxidation.
