Preparation of reduced graphene oxide nanosheet/FexOy/nitrogen-doped carbon layer aerogel as photo-Fenton catalyst with enhanced degradation activity and reusability

Nanotechnology activities: environmental protection regulatory issues data

“…Thus, it can be said that in this period, studies on the application of nanotechnology in environmental issues, such as soil remediation and decontamination of other environmental matrices, and not studies on the environmental impact of nanoparticles, were highlighted. This finding has already been confirmed by the scientific literature, which shows that the application of various types of engineered nanomaterials has gained attention in recent years [29,30,31]. In this sense, several metallic and non-metallic compounds were synthesized and used in order to remove various environmental contaminants [32,33,34].…”

The Efficient Photocatalytic Degradation of Organic Pollutants on the MnFe2O4/BGA Composite under Visible Light

“…Figure 3 d displays the FT-IR spectra of as-synthesized MnFe 2 O 4 , BGA, and MnFe 2 O 4 /BGA composite. It is clear that the bands ascribed to the sp 2 -hybridized C=C in-plane, the B-C, and O-B-O bond stretching vibrations are observed at 1573, 1030, and 655 cm −1 , respectively [ 27 , 28 , 29 ], indicative of the successful doping of boron in the graphene frameworks both in BGA and in MnFe 2 O 4 /BGA composite [ 30 ]. The peak at about 1721 cm −1 is due to the C=O stretching vibrations from carbonyl.…”

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

“…Notably, an additional peak at 531.1 eV appeared, probably due to the formation of Fe-O-C bond between PPy and Fe 2+ , which is benecial for the rapid transfer of electrons during the photo-Fenton reaction. 52 The PPy coating also reduced the relative strength of Fe and Co. From Fig. 5e, the three characteristic peaks with binding energies of 780.05 AE 0.2 eV, 781.89 AE 0.2 eV and 785.9 eV are ascribed to Co 2p 3/2 .…”
