Graphene oxide enhances the Fenton-like photocatalytic activity of nickel ferrite for degradation of dyes under visible light irradiation

Catalytic activity of the barium hexaferrite with H2O2/visible light irradiation for degradation of Methylene Blue

“…The presence of HO • especially favors the decomposition of unsaturated compounds in aqueous solution [2] and due to its high oxidation potential (2.80 V) [1,9], it is capable to oxide and mineralize almost any organic molecule producing water, carbon dioxide, and other inorganic substances [1][2][3].…”

“…The heterogeneous photo-assisted Fenton-like system employs the use of a visible light activated heterogeneous catalysts, which are semiconductor materials [9] with magnetic properties and the advantage of providing a wide working range of pH [5].…”

Synthesis of magnetic CoFe2O4/ordered mesoporous carbon nanocomposites and application in Fenton-like oxidation of rhodamine B

“…Secondly, the oxygen-containing functional groups on OMC surface can serve as the anchoring points and reduce surface energy of CoFe 2 O 4 nanoparticles, which is helpful to their good distribution. This is beneficial for enhancing the mass transfer of RhB and PMS toward the active sites during the reaction (Liu et al 2013 Hu et al 2013;Lin & Chang, 2015).…”

Beading of cobalt substituted nickel ferrite nanoparticles on the surface of carbon nanotubes: a study of their synthesis mechanism, structure, magnetic, optical and their application as photocatalyst.

“…Significant enhancement in the photoactivity of ferrite nanoparticles in combination with MWCNTs was reported due to the synergetic effect. Liu et al [12] prepared graphene oxide-NiFe 2 O 4 nanocomposite, which was utilized in photo-Fenton process for the degradation of organic dyes using oxalic acid and hydrogen peroxide.…”
