摘要：

A newly nonenzymatic sensor for hydrogen peroxide (H2O2) based on the (Au-HS/SO3H-PMO (Et)) nanocomposite is demonstrated. The electrochemical properties of the as-prepared nanocomposite were studied. It displayed an excellent performance towards H2O2 sensing in the linear response range from 0.20 mu M to 4.30 mu M (R=0.9999) with a sensitivity of 6.35 x 10(2) mu A mu M-1 cm(-2) and a low detection limit of 0.0499 mu M. Furthermore, it was not affected by electroactive interference species. These features proved that the modified electrode was suitable for determination of H2O2.
