Preparation and Photoelectronic Properties of Zinc Oxide/Perovskite Nanocomposites/Polypyrrole

Abstract:

La0.3Ca0.7Fe0.7Ni0.3O3 perovskite-type composite was prepared by glycine-nitrate combustion method , Zinc Oxide was prepared by liquid crystal precipitation, then we synthesized ZnO/La0.3Ca0.7Fe0.7Ni0.3O3/Ppy nanocomposites with different content of Ppy in situ method. XRD,SEM,UV-vis were used to characterized the crystal structure and morphology of the nanocomposites and their photocatalytic activity. Cyclic voltammetry of the composites were conducted in 1mol/L KCl solutions to discuss their electrochemical properties.According to the electrochemical properties, we found that with the increase of the zinc oxide content,the redox peak current of the composites becomes larger, also their reversible redox properties was improved.
