Magnetic recyclable CoFe₂O₄@PPy prepared by in situ Fenton oxidization polymerization with advanced photo-Fenton performance

Abstract

Here we present a magnetic recyclable photo-Fenton catalyst CoFe2O4@PPy with uniform morphology and excellent dispersibility prepared via simple in situ Fenton oxidization polymerization.

Development of Durian Rind/Polypyrrole Composite and Its Application in Removing of Anionic Dyes

“…The XRD pattern of PPy has a broaden diffraction peak at 15-30 °due to the amorphous feature of PPy. The result was in conformity with the literature [16,17]. In the XRD pattern of DR/PPy, characteristic diffraction peak of 22.1 °related to PPy is integrated with the cellulose peak of DR, which is consistent with the related phenomenon reported in our previous report [1].…”

Cooperative Design of the Ag3PO4/NH2-MIL-88B (Fe/Co) Heterojunction Integrated with Conductive Polypyrrole for Advanced Photocatalytic Water Purification

“…From Figure c of N 1s spectra, a peak appeared at ∼398.0 eV for MIL@f, Ag/MIL@f, and Ag/PPy/MIL@f, which correspond to −NH 2 groups in BDC–NH 2 (aminoterephthalic acid) of MIL. In comparison to MIL@f, Ag/MIL@f displayed a higher intensity of C–N peak (399.8 eV), due to the electron density change attributable to interactions between MIL and Ag 3 PO 4 . , The Ag/PPy/MIL@f showed a higher intensity for C–N than for – NH 2 (Figure S7), due to the presence of pyrrolic C–N in PPy . Ag/PPy/MIL@f showed a new peak at 401.4 eV corresponding to the Fe–N pyrrole bond due to the successful PPy synthesis on the MIL surface.…”

“…50,54 The Ag/PPy/MIL@f showed a higher intensity for C−N than for − NH 2 (Figure S7), due to the presence of pyrrolic C−N in PPy. 58 Ag/PPy/MIL@f showed a new peak at 401.4 eV corresponding to the Fe− N pyrrole bond due to the successful PPy synthesis on the MIL surface. The Fe−N pyrrole bond could contribute to the coexistence of Fe 2+ /Fe 3+ in Ag/PPy/MIL@f. 59 Photoelectrochemical Characterization.…”

Review on cobalt ferrite as photo-Fenton catalysts for degradation of organic wastewater

“…Non-metallic carbides and macromolecule polymers that are compounded with CoFe 2 O 4 as the photo-Fenton catalyst mainly include activated carbon, graphene, g-C 3 N 4 , and PPy. 28,55,108,109 These catalytic materials can often enhance the electrical conductivity of composite catalysts, facilitate the transfer of charge carriers, and expose more CoFe 2 O 4 active sites. Bagherzadeh et al prepared a MIL-101(Fe)/CoFe 2 O 4 /GO ternary composite catalyst, and tested its catalytic performance for azo dyes.…”
