摘要：

The morphologies, roughness factors. and thicknesses of 3D nanoporous Pt (3D-npPt) films were investigated in terms of electroplating conditions. The electrochemical behaviors of 3D-npPt films with regard to electrochemical glucose oxidation, O-2 reduction. and H2O2 reduction were investigated as a function of roughness factors (Rf) Close comparison of glucose oxidation on 3D-npPt and 1D nanoporous Pt (1D-npPt) showed that the overall electrode activity of 3D-npPt is significantly higher than that of 1D-npPt Electrochemical impedance analysis based on transmission line theory confirmed a substantially low pore resistance of 3D-npPt. which may account for the superior electrode response of this material.
