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

“…We previously reported pure nickel ferrite (NiFe 2 O 4 ) as a heterogeneous photo-Fenton catalyst for the degradation of organic dyes in the presence of oxalic acid under UV light irradiation [33]. The material had almost no catalytic response to visible light although diffuse reflection measurements showed that the start point of the NiFe 2 O 4 spectrum occurs at 788 nm [34,35]. In the current study, we present the combination of graphene oxide (GO) with NiFe 2 O 4 to prepare GO-doped nickel ferrite (GO-NiFe 2 O 4 ) and examine the photo-Fenton catalytic response of the GO-NiFe 2 O 4 catalyst to visible light.…”

Magnetic response and adsorptive properties for methylene blue of CoFe 2 O 4 /Co x Fe y /activated carbon magnetic composites

“…Kadirova et al [19][20][21] synthesized magnetic Fe 2 O 3 /AC composites by impregnation method for methylene blue removal and magnetic separation. Feng et al [22] synthesized NiFe 2 O 4 /AC composites by the hydrothermal method for degradations of the model pollutants of MB, rhodamine B and malachite green.…”
