Abstract

Abstract: In this letter, we demonstrate for the first time that cobalt phosphide nanowires (CoP NWs) exhibit remarkable catalytic activity toward electrochemical detection of hydrogen peroxide (H2 O2 ). As an enzymeless H2 O2 sensor, such CoP NWs show a fast amperometric response within 5 s and a low detection limit of 0.48 μ M. In addition, this nonenzymatic sensor displays good selectivity, long-term stability and excellent reproducibility.
