摘要

A novel method to construct a sensitive amperometric sensor for hydrogen peroxide (H2O2) is described. It is composed of highly dispersed palladium nanoparticles on a vertically aligned nickel-coated silicon micro-channel plate (MCP). The morphology of the Pd/Ni/Si-MCP electrode is characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The electrode with a three-dimensional structure shows high-catalytic activity towards oxidation of H2O2 in a 0.10 M KOH solution. The electrode boasts a high sensitivity of 0.86 mAmM-1cm-2 at an applied potential of 0.12V, and the detection limit is 7.6μM. The linear range is up to 12.5mA with a linear correlation of 0.99923. In addition, the electrode also exhibits superior stability, anti-interference, and selectivity. These features demonstrate the Pd/Ni/Si-MCP electrode is suitable for detection of H2O2.
