Controlled photocatalytic activity of modified PTFE fiber-Fe complex through layer-by-layer self-assembly of poly diallyldimethyl ammonium choloride and poly styrene sulfonate

摘要

Graphical abstract Novel heterogeneous photo-Fenton catalyst was fabricated on the acrylic acid grafted PTFE fiber through a layer-by-layer self-assembly process with poly diallyldimethyl ammonium choloride (PDDA) and poly styrene sulfonate (PSS) and subsequent Fe3+ ion coordination, and significantly enhanced the degradation of organic dye in water under visible irradiation. Display Omitted Highlights ? A PDDA/PSS multilayer was fabricated on PTFE fiber by self-assembly process. ? It coordinated with Fe3+ to produce a modified PTFE fiber Fe complex. ? The complex was used as heterogeneous Fen
