A kind of poly- 3,4- ethylenedioxy thiophene/biomass carbon/SnO 2‑x The preparation method of nanocomposite, by SnO 2‑x Load is scattered in nanocomposite obtained from poly- 3,4- ethylenedioxy thiophene by way of chemical bond is complexed with biomass carbon heterojunction semiconductor.The present invention utilizes SnO 2‑x Visible light photocatalysis redox characteristic, biomass carbon superior electrical conductivity, poly- 3, there is the heterojunction structure of chemical bonding between the electric conductivity and component of 4- ethylenedioxy thiophene, sufficiently inhibit the photo-generate electron-hole in its light-catalyzed reaction compound, to be conducive to improve the performance of its photocatalytic redox degradation of contaminant and photocatalysis Decomposition aquatic products hydrogen.Meanwhile the characteristics of conductive organic matter easy plastotype, can effectively avoid the recycling difficult problem of powder body material, thus, poly- 3,4-ethylene dioxythiophene (PEDOT)/biomass carbon/SnO produced by the present invention 2‑x Nanocomposite is a kind of novel environment friendly catalysis material convenient for recycling. |
