In this manuscript, the electrocatalytic reduction of hydrogen peroxides on Prussian blue (PB) modified nanoporous gold film (NPGF) electrode is described. The PB/NPGF is prepared by simple anodizing of a smooth gold film followed by PB film electrodeposition method. The morphology of the PB/NPGF electrode is characterized using scanning electron microscopy (SEM). The effect of solution pH and the scan rates on the voltammetric responses of hydrogen peroxide have also been examined. The amperometric determination of H2O2 shows two linear dynamic responses over the concentration range of 1μM-10μM and 10μM-100μM with a detection limit of 3.6×10(-7)M. Furthermore, this electrode demonstrated good stability, repeatability and selectivity remarkably.
在本文中，描述了在普鲁士蓝（PB）修饰的纳米多孔金膜（NPGF）电极上过氧化氢的电催化还原。PB/NPGF 通过简单的金膜阳极氧化后 PB 膜电沉积方法制备。使用扫描电子显微镜（SEM）对 PB/NPGF 电极的形态进行了表征。还研究了溶液 pH 值和扫描速率对过氧化氢伏安响应的影响。H2O2 的安培测定在 1μM-10μM 和 10μM-100μM 的浓度范围内显示出两个线性动态响应，检测限为 3.6×10(-7)M。此外，该电极表现出良好的稳定性、重现性和选择性。
