摘要: Abstract In this manuscript, the electrocatalytic reduction of hydrogen peroxides on Prussian blue (PB) modified nanoporous gold film (NPGF) electrode is described. The PB/NPGF prepared by simple anodizing a smooth followed PB electrodeposition method. morphology characterized using scanning electron microscopy (SEM). effect solution pH and scan rates voltammetric responses peroxide have also been examined. amperometric determination H2O2 shows two linear dynamic over concentration range 1 μM–10 μM 10 μM–100 μM with detection limit 3.6 × 10− 7 M. Furthermore, demonstrated good stability, repeatability selectivity remarkably.
