Electrospun magnetic CoFe₂O₄/Ag hybrid nanotubes for sensitive SERS detection and monitoring of the catalytic degradation of organic pollutants

Abstract

We report on the synthesis of magnetic CoFe2O4/Ag hybrid nanotubes as both SERS substrate and catalyst to monitor the catalytic degradation process of organic pollutants.

“…37 The combination of Au/Ag NPs with AgFeO 2 can effectively enhance the SERS sensitivity by rapid aggregation in a small area in the solution to enrich PE molecules and by the enhancement of the electromagnetic field from the interaction between the Au/Ag NPs and AgFeO 2 . 38 Thus, the intensity enhancement of the Raman signal of PE is attributed to the plasmonic coupling of Au/Ag NPs and the charge transfer between the Au/Ag NPs and AgFeO 2 . Considering these facts, AgFeO 2 interlinked with Au/Ag NPs is a promising candidate for SERS applications.…”

Electrospun Fe2C-loaded carbon nanofibers as efficient electrocatalysts for oxygen reduction reaction

“…After the solvent was fully evaporated in the air, perfect Janus structured NFs were formed in which FeAc 2 /PVP and PAN were separated on each side of the NFs, respectively. In the carbonization process [33], the PAN was carbonated and finally converted to carbon while the PVP was decomposed and Fe 2 C nanocrystals were formed [34]. By using this fabrication method, the Fe 2 C nanocrystals tended to be uniformly distributed on the surface of carbon NFs, led to the increase in the contact area of Fe 2 C and H 2 O during the catalysis process without hindering the conductivity of the carbon NFs.…”

Recent advances in electrospun magnetic nanofibers and their applications

“…Electrospinning technology is widely used in waste water treatment methods such as membrane separation, 176 adsorption and catalytic pollutants. [177][178][179][180][181] Membrane separation technology uses semipermeable membranes to selectively permeate molecules of different sizes to separate pollutants in water. For example, Shengqiu Chena and others have successfully synthesized poly(sulfobetaine methacrylate)/poly(ether sulfone) (PSBMA/ PES) electrospun fiber membranes with excellent water-oil separation performance.…”
