摘要：
We report on the electrocatalytic reduction of hydrogen peroxide at nanoporous gold (NPG) surfaces. Various NPG surfaces with different surface structure were prepared by changing the conditions of electrodeposition for Ag-Au layers such as the concentration ratios of KAu(CN)(2) over KAg(CN)(2) and deposition charges. The effects of different electrochemical conditions on the electrocatalysis of H2O2 reduction were investigated. The NPG surfaces exhibited sensitive amperometric responses for H2O2 reduction, from which calibration plots with higher sensitivity than a bare Au surface were obtained.
