Abstract

New copper complex compounds composed of 2,4,6-tris(2-pyridylmethylamino)- 1,3,5-triazine (TPMATA) and CuCl2/CuSO4 in water or ionic liquid (IL) were prepared. Two approaches were used to fix the copper complexes to the IL carbon paste electrodes through our previous one-step method. IL shows its advantage over the traditional organic binder paraffin oil because the electrodes demonstrated much higher activity towards hydrogen peroxide reduction. After introducing TPMATA-CuCl2 dissolved in IL to the electrode, the electrode shows the best current response and selectivity to hydrogen peroxide reduction.
