摘要

Poly(5-cyanoindole) (P5CN), an excellent electron and proton conducting polymer, was incorporatedwith highly dispersed and small sized Pt-Cu nanoclusters on a glassy carbon (GC) electrode byelectrochemical co-electrodeposition. The Pt-Cu nanoclusters-decorated P5CN (Pt-Cu/P5CN/GC)shows remarkable electrocatalytic activity toward methanol and formic acid oxidation in acid medium.The morphological characterizations by the scanning electron microscopy (SEM) and transmissionelectron microscopy (TEM) demonstrate the porous structure of P5CN and good dispersion of Pt-Cunanoclusters with small diameter. The energy dispersive X-ray spectroscopy (EDX) and X-rayphotoelectron spectrometer (XPS) also confirm the components of Pt-Cu/P5CN composites and theirelectronic structures. The cyclic voltammetric and chronoamperometric methods were used toinvestigate the catalytic activity and stability of as-prepared catalysts. The experimental results indicatethat the P5CN as support and Cu introduced into Pt enhance the catalytic activity.
