One kind poly- 3,4- ethylenedioxy thiophene/auto-dope richness defect tin oxide nano composite photocatalyst material preparation method, by the tin oxide heterogeneous knot material of auto-dope richness defect, the load by way of chemical bond is complexed is scattered in nanocomposite obtained from PETOT to the present invention；Auto-dope richness defect tin oxide is selected from the non-stoichiometric of Sn doping or the rich defect tin oxide SnO of mixed valence tin-oxide composition 2‑x .The present invention utilizes the redox ability of the tin oxide heterogeneous knot material visible-light response of auto-dope richness defect, the electric conductivity and cavity transmission ability of PETOT, and there is the heterojunction structure of chemical bonding between different component, to be conducive to electron hole separation, excellent photocatalysis performance is obtained.Simultaneously, the characteristics of polypyrrole easy plastotype, can effectively avoid the recycling difficult problem of powder body material, thus, the tin oxide heterogeneous knot nanocomposite of poly- 3,4-ethylene dioxythiophene/auto-dope richness defect produced by the present invention is a kind of novel environment friendly catalysis material convenient for recycling. |
