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