Synthesis of Magnetic Recoverable Electron-rich TCTA@PVP based Conjugated Polymer for Photocatalytic Water Remediation and Disinfection

In this study, we report the synthesis of magnetic electron-rich CP@Fe3O4(Conjugated Polymer (CP) = TCTA-PVP-bipyridine) by hydrothermal method. For this aim, the Fe3O4nanoparticles were incorporated into photoactive TCTA-PVP-bipyridine based Conjugated Polymer. The photo-redox abilities of CP@Fe3O4and bare CPwere tested for oxidation of methylene blue and reduction of Cr(VI) under UV–visible light and visible light(λ> 420 nm). The CP@Fe3O4showed a good ability for performing the Fenton-like reaction by adding H2O2asoxidizing agent. Additionally, reveals high photocatalytic reduction ability of Cr(VI) for CP@Fe3O4in compare with bare CP. Furthermore the photocatalytic antibacterial ability of CP@Fe3O4towardsE. coliandPseudomonasAerogenosain water was studied. The obtained CFU reduction efficiencies were found about 85% and 90% forE.coliandP. Aeruginosa, respectively. Interestingly the collecting and recyclability of CP@Fe3O4after photo-catalytic reactions were done easily due to its magnetic property.
