摘要: Poly(5-cyanoindole) (P5CN), an excellent electron and proton conducting polymer, was incorporated with highly dispersed and small sized Pt-Cu nanoclusters on a glassy carbon (GC) electrode by electrochemical 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 transmission electron microscopy (TEM) demonstrate the porous structure of P5CN and good dispersion of Pt-Cu nanoclusters with small diameter. The energy dispersive X-ray spectroscopy (EDX) and X-ray photoelectron spectrometer (XPS) also confirm the components of Pt-Cu/P5CN composites and their electronic structures. The cyclic voltammetric and chronoamperometric methods were used to investigate the catalytic activity and stability of as-prepared catalysts. The experimental results indicate that the P5CN as support and Cu introduced into Pt enhance the catalytic activity.
