Magnetically separable and reusable rGO/Fe₃O₄ nanocomposites for the selective liquid phase oxidation of cyclohexene to 1,2-cyclohexane diol

Abstract

A series of magnetically-separable and reusable rGO/Fe3O4 nanocomposites were successfully synthesized for the selective liquid-phase oxidation of cyclohexene to 1,2-cyclohexane-diol.

Laser Processed Magnetite Nanoparticles Embedded on rGO Composites for Efficient Electrocatalytic Oxygen Evolution Reaction

“…The strong interactions of Fe 3 O 4 nanoparticles with rGO can be illustrated by the formation of COFe bond. [ 45–48 ] The O 1s deconvoluted peak (Figure 3b) follows the same trend, where the deconvoluted peak at 530.1 eV is assigned to the OFe bond (lattice oxygen of (Fe 3 O 4 ). [ 45,46,49 ] The broad peak could be related to oxygen functionalities such as OCO, CO after the partial reduction of GO under laser irradiation.…”

Pb(Ⅱ) adsorption characteristics of magnetic GO-hydroxyapatite and the contribution of GO to enhance its acid resistance

“…The corresponding equations were provided in the Supplementary material. (Pudukudy et al, 2019), while O1s (Figure 2c) peaks were ascribed to Fe3O4 (530.0 eV), C=O (531.5 eV) and C-O (532.8 eV) bonds (Guo et al, 2016). Moreover, Ca2p (Figure 2d, 347.6 eV, 351.2 eV) and P2p (Figure 2e, 133.1 eV, 133.8 eV) peaks (López et al, 2019;Lovón-Quintana et al, 2017) verified the presence of HAP in PMGO.…”

“…Graphene oxide (GO) has been reported to have more uniform dispersion in the synthetic magnetic materials (Fang et al, 2016). Furthermore, it is able to inhibit the selfpolymerization of Fe3O4 (Pudukudy et al, 2019). Thus, it has a broad application prospect in the field of magnetic materials.…”

Morphological Evolutions of Ti3C2Tx Nanosheets and Fe3O4/Ti3C2Tx Nanocomposites under Potential Cycling Investigated Using In Situ Electrochemical Atomic Force Microscopy

“…The Fe 2p spectrum of the Fe 3 O 4 /Ti 3 C 2 T x nanocomposites contained two main peaks at 710.4 and 723.4 eV belonging to the characteristic peaks of Fe 2+ and the other two peaks at 712.9 and 725.9 eV corresponding to the characteristic peaks of Fe 3+ (Figure S2B). , This indicated that the loaded iron oxide was Fe 3 O 4 . The above characterization results showed that the Ti 3 C 2 T x nanosheets and Fe 3 O 4 /Ti 3 C 2 T x nanocomposites have been successfully synthesized.…”

“…23−28 As for the Fe 3 O 4 /Ti 3 C 2 T x nanocomposites (Figure S1A), in characteristic peaks of Fe 3+ (Figure S2B). 30,31 This indicated that the loaded iron oxide was Fe 3 O 4 . The above characterization results showed that the Ti 3 C 2 T x nanosheets and Fe 3 O 4 / Ti 3 C 2 T x nanocomposites have been successfully synthesized.…”
