Abstract
In this paper, we synthesized flowerlike silver microspheres with nanostructures by simply reducing silver nitrate by ascorbic acid in the presence of PVP. The structure was investigated by SEM. The chemical composition was determined by EDX, XRD and XPS. Recent studies on hydrogen peroxide sensor based on silver nanoparticles inspired us to examine the electrocatalytic activity of prepared microspheres. This electrochemical sensor exhibited good electrocatalytic activity towards the reduction of H2O2 in 0.2 M phosphate buffer solution (pH 7.0), and the detection limit of H2O2 was found to be 1.2 μM, which was lower than certain enzyme-based biosensors.
