Adsorption and heterogeneous Fenton catalytic performance for magnetic Fe3O4/reduced graphene oxide aerogel

Magnetite–reduced graphene oxide nanocomposite as an efficient heterogeneous Fenton catalyst for the degradation of tetracycline antibiotics

“…7b), the peaks for Fe 2p 3/2 and Fe 2p 1/2 are seen at 709.6 eV and 723.2 eV, respectively, as well as the absence of a satellite peak at 719 eV, which is also suggestive of the development of a pure Fe 3 O 4 phase in the MG10 matrix. 46,53,54 When the binding energy peaks of O 1s are deconvoluted, the peak at 528.1 eV is attributed to magnetite lattice oxygen, 55 whereas the peak at 530.2 eV is attributed to residual oxygen in rGO sheets (Fig. 7c).…”

Facile Synthesis Strategy from Sludge-Derived Extracellular Polymeric Substances to Nitrogen-Doped Graphene Oxide-Like Material and Quantum Dots

“…The adsorption capacity was first increased and then decreased with the increase of nitrogen doping, and when the atomic ratio of N/C was between 0.062 and 0.073, nitrogen-doped GO reached its strongest adsorption ability . Fe 3 O 4 nanoparticle modification was demonstrated to make GO an attractive adsorbent with enhanced adsorption ability . Sulfur doping also contributes to improving the adsorption ability of GO for removal of cesium ions .…”

“…48 Fe 3 O 4 nanoparticle modification was demonstrated to make GO an attractive adsorbent with enhanced adsorption ability. 49 Sulfur doping also contributes to improving the adsorption ability of GO for removal of cesium ions. 50 Moreover, a large surface area with a porous structure of the prepared N-GO was determined by BET, which was reported to play an important role in the adsorption ability of nanomaterials.…”

CoAl-LDHs@Fe3O4 decorated with cobalt nanowires and cobalt nanoparticles for a heterogeneous electro-Fenton process to degrade 1-hydroxyethane-1,1-diphosphonic acid and glyphosate

“…^Fe II and ^Co II could be regenerated, as shown in eqn ( 8) and ( 9), and cOOH was simultaneously produced. 60 cOOH and cO 2 À could be converted into each other, as shown in eqn (10). 61 The synthesis processes of CoNWs@CoAl-LDHs/Fe 3 O 4 and CoN-Ps@CoAl-LDHs/Fe 3 O 4 are shown in Fig.…”
