摘要：
The poly(o-phenylenediamine) (PoPD) film modified with highly dispersed platinum microparticles causes a great increase in electroactivity and the electrocatalytic reduction for hydrogen peroxide. The different metal-polymer configuration will strongly affect the electrochemical behavior and electrocatalytic activity of the composite film. The dependences of catalytic response on the potential scan rate, the pH, and the concentration of species are studied in detail. (C) 1999 Elsevier Science S.A. All rights reserved.
