Abstract:
A new copper dispersed ceramic-graphite composite electrode was fabricated by the initial mixing of copper nitrate and (3-mercaptopropyl)trimethoxy silane (MPS) followed by stirring with graphite powder. The combination of the metal catalysis and the advantages of the ceramic composite favored the electrocatalytic reduction of hydrogen peroxide (H2O2) at a reduced overpotential of -0.2 V with good sensitivity, stability and reproducibility. The sensor showed a good linear response to H2O2 in the range from 8.3 x 10(-6) M to 2.0 x 10(-3) M with a correlation coefficient of 0.9989 and the detection limit was 6.2 x 10(-6) M (S/N =3).

The Standard Hydrogen Electrode (SHE) is a widely used reference electrode that maintains zero potential across all temperatures. However, its need for a continuous hydrogen gas supply renders it impractical for everyday use.
An alternative to SHE is the Saturated Calomel Electrode (SCE). This electrode features an...
