摘要：

A composite material of polybithiophene (PBTh) and beta-MnO2 was prepared by electrodeposition of organic conducting polymer on beta-MnO2 surface in 0.1 M LiClO4/0.01 M BTh/CH3CN. Synthesized material was characterized by using various techniques, i.e., X-ray diffractometry (XRD), scanning electron microscopy (SEM), and magnetic measurements (SQUID). Electrochemical features of oxygen reduction reaction were investigated using cyclic voltammetry on beta-MnO2 and PBTh/beta-MnO2 electrode, and chronopotentiometry tests were carried out at different currents. The results show that peak current and potential of oxygen reduction are changed for beta-MnO2 modified by polybithiophene.
