摘要

This study reports on the preparation of Pt- and Ru-based electrocatalysts through electrodeposition of Pt and Ru particles into the nanofibrous network of polyaniline (PANI)-poly(styrene sulfonic acid) (PSS). The sequence of electrodeposition of Pt and Ru particles was changed and the electrocatalysts, PANI-PSS-Pt-Ru and PANI-PSS-Ru-Pt, were obtained. Scanning electron microscopy (SEM), X-ray photoelectron microscopy (XPS), and cyclic voltammetry (CV) were employed to investigate the morphology, structural and electrochemical properties of the electrocatalysts, PANI-PSS-Pt-Ru and PANI-PSS-Ru-Pt. The distribution of Pt and Ru particles into PANI-PSS matrix was analyzed by the Auger depth profiles. The electrochemical behavior PANI-PSS-Pt-Ru and PANI-PSS-Ru -Pt and the electrocatalytic behavior toward oxidation of methanol were evaluated by cyclic voltammetry. PANI-PSS-Ru-Pt exhibited a superior electrocatalytic performance for methanol oxidation as compared to PANI-PSS-Pt-Ru.
