“…The 551 and 1049 cm −1 broad peaks were attributed to the octahedral spinel structure of CuFe 2 O 4 NPs. The weak peak transfer of 476 cm −1 to the two regions 551 and 1049 cm −1 confirmed the transfer of the O stretching bond from the tetrahedral location to the octahedral location 108 , 109 . The peaks of 3449 and 3346 cm −1 can be attributed to the stretching vibration of O–H group of nasturtium (plant) phenolic compounds.…”

Zn-doped CuFe2O4 nanoparticles (NPs) were eco-friendly synthesized using plant extract. These nanoparticles were characterized by X-ray diffraction, Fourier-transform infrared spectroscopy, scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy and thermal gravimetric analysis (TGA). SEM image showed spherical NPs with size range less than 30 nm. In the EDS diagram, the elements of zinc, copper, iron, and oxygen are shown. The cytotoxicity and anticancer properties of Zn-doped CuFe2O4 NPs were evaluated on macrophage normal cells and A549 lung cancer cells. The cytotoxic effects of Zn-doped CuFe2O4 and CuFe2O4 NPs on A549 cancer cell lines were analyzed. The Zn-doped CuFe2O4 and CuFe2O4 NPs demonstrated IC50 values 95.8 and 278.4 µg/mL on A549 cancer cell, respectively. Additionally, Zn-doped CuFe2O4 and CuFe2O4 NPs had IC80 values of 8.31 and 16.1 µg/mL on A549 cancer cell, respectively. Notably, doping Zn on CuFe2O4 NPs displayed better cytotoxic effects on A549 cancer cells compared with the CuFe2O4 NPs alone. Also spinel nanocrystals of Zn-doped CuFe2O4 (~ 13 nm) had a minimum toxicity (CC50 = 136.6 µg/mL) on macrophages J774 Cell Line.

“…The peak at 1147 cm -1 is attributed to -C-O stretching vibration of carboxylic acids and alcohols [47][48][49]. After modification of the DS with CuFe2O4 nanoparticles, we note the presence of the peaks at 586 cm −1 and 475 cm −1 corresponds to the Fe and Cu [50][51][52], respectively. These peaks confirmed the complexation of CuFe2O4 nanoparticles with DS.…”

In this study, the date stones/CuFe2O4 nanocomposite was synthesized by a graft of CuFe2O4 nanoparticles in the surface of date stones (DS) for the removal of rhodamine B (RhB) and methyl orange (MO) from aqueous solutions. The adsorption of RhB and MO on DS@CuFe2O4 shows good agreement with second-order kinetic and Langmuir isotherm models. The maximum adsorption capacity was found to be 555.56 03 mg g -1 and 303.03 mg g -1 for RhB and MO, respectively.This adsorption is spontaneous and endothermic. There is excellent regeneration and high reusability of the DS@CuFe2O4 for the RhB and MO removal in six cycles.

“…In Figure a (inset), GO showed a sharp diffraction peak at 2θ = 10.60° representing (002) plane (DB card number 9012590), and the interlayer distance of ∼0.8 nm indicates the presence of functional group of GO . In XRD pattern of 5% GO–CuFe 2 O 4 hybrid catalyst, the diffraction peaks at 2θ = 18.39°, 30.18°, 35.49°, 37.02°, 43.08°, 53.40°, 56.86°, 62.51°, and 66.46° represent the crystal planes of (111), (220), (311), (222), (400), (422), (511), (440), and (531) of spinel CuFe 2 O 4 (DB-9012841). − Besides this, weak diffraction peaks at 2θ = 38.93°, 48.94°, and 68.31° for the crystal planes of (111), (202), and (113), respectively, of tenorite phase (DB-1011148) appeared due to the presence of trace amount of CuO. Similar crystal plane and angles of diffraction values were observed in our previous study for CuFe 2 O 4 catalyst .…”

Photoelectrocatalytic reduction of CO 2 into valuable products can provide energy in a sustainable way with leveling off of the concentration of CO 2 in our environment. In this study, graphene oxide (GO) incorporated with copper ferrite (CuFe 2 O 4 ) has been employed to enhance photoelectrocatalytic CO 2 reduction under visible light. The TEM and XPS characterization indicated a strong interaction between the CuFe 2 O 4 and GO in the hybrid catalyst. The GO incorporation reduced the e − /h + recombination in the hybrid catalyst by trapping the photoexcited electrons from CuFe 2 O 4 leading to high methanol yield of 28.8 μmol L −1 cm −2 at 20.5% quantum efficiency. The incident photon current efficiency (IPCE) and Faradaic efficiency for methanol formation were observed as 8.02% and 87%, respectively. The results showed that the photoelectrocatalytic activity for CO 2 reduction can be improved by incorporating GO with CuFe 2 O 4 , and it provides a universal platform to fabricate GO−CuFe 2 O 4 based hybrid photocatalyst with promising applications in CO 2 reduction.
