[Abstract]:In recent years, the research of organic polymer-inorganic nanocomposites has become a very vitality research field, this kind of material will have the hope in optics, electromagnetism, mechanics, As a new type of semiconductor material, ZnO has been widely used in many fields such as biology, because of its unique catalytic, electrical and optoelectronic properties. Conductive polymers, mainly Polyaniline and polypyrrole, have gradually become the focus of research because of their unique properties. In this thesis, binary and ternary complexes containing ZnO and conductive polymers were prepared, and their photocatalytic and electrochemical properties were studied. The specific contents of the study are as follows: (1) Ppy was prepared by in situ compounding, and ZnO / Ppy20 / Ppy20 / (6060D) composites with different Ppy content were prepared by hydrothermal method. The morphology of the samples was characterized by FT-IRT, SEM (SEM) and X-ray diffraction (XRD). The results showed that the morphology of the complex was more uniform at 60th time, and the catalytic performance of the complex was studied by photocatalytic degradation of methyl orange dye. The results showed that the catalytic performance of the complex was better when the content of Ppy was 60%. The electrochemical properties of the sample were preliminarily studied by using the complex self-made study electrode, the cyclic voltammetry curve was determined by the three-electrode system, and the symmetrical redox peak was obtained when the relative mass was 60. La0.3Ca0.7Fe0.7Ni0.3O3 perovskite complex oxides were prepared by glycine nitrate combustion at different temperatures (200 鈩，
