| Abstract: | The graphene paste electrode (GPE), modified with platinum nanoparticles (NPt), is fabricated and characterized by electrochemical impedance spectroscopy and cyclic voltammetry. Borohydride electrooxidation and hydrogen evolution reaction (HER) are investigated by cyclic voltammetry at surface of the fabricated electrode. Linear sweep voltammetry of NPt/GPE and NPt/carbon paste electrode in different concentrations of borohydride was studied. Results demonstrate good conductivity and electrocatalytic activity of NPt/GPE toward borohydride electrooxidation and HER. The morphology of platinum nanoparticles is studied by atomic force microscopy. |
