“…The hysteresis loop recorded at 300 K shows the early magnetization saturation at a very low applied magnetic field of ∼8 kOe, indicating ferromagnetic nature. The observed magnetization at an applied field of 10 kOe is ∼54 emu g −1 , higher than the reported values for NiFe 2 O 4 nanoparticles [27][28][29][30][31][32]. The observed saturation magnetization at 20 kOe is 55 emu g −1 , corresponding to 2.32 μ Β -one of the highest values reported in the literature and highest among the green synthesized NiFe 2 O 4 (table 2) [27][28][29][30][31][32].…”

“…These are becoming increasingly popular because of their attractive properties, such as low toxicity, use of renewable resources, and the ability to degrade toxic organic waste materials. So far, little literature has reported on the green synthesis of NiFe extract as surfactant via co-precipitation method and resulted in average particle size of 27 nm, agglomerated morphology, and M s of 33 emu g −1 at an applied field of 10 kOe [29]. Manju et al have reported the green synthesis of NiFe 2 O 4 nanoparticles using Aloe barbadensis extract as a surfactant, resulting in M s of 3.51 emu g −1 at an applied field of 15 kOe [30].…”

Spinel NiFe2O4 nanoparticles have been synthesized via hydrothermal route using Mangifera indica flower extract (MIFE) as a green surfactant and reducing agent. X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and transmission electron microscopy techniques have been used to determine the structure and morphology. The formation of single-phase, monodispersed NiFe2O4 with mixed morphology, the predominant shape being of equi-axed nanoparticles having an average particle size ≲45 nm, is observed. The thermal magnetization of as-synthesized NiFe2O4 nanoparticles shows ferromagnetic to paramagnetic phase transition at T c ∼ 825 K. These nanoparticles show a very high saturation magnetization (M s) value of 55 emu g−1 close to the bulk material and amongst the highest reported values for green synthesized NiFe2O4 nanoparticles. This material has a coercivity (H c) of 0.15 kOe and remanent magnetization (M r) of 8.5 emu g−1. The as-synthesized NiFe2O4 nanoparticles show bandgap energy of 2.02 eV, derived from UV–vis absorption measurement, which is suitable for effective solar photocatalytic reactions. When exposed to sunlight in the presence of as-synthesized NiFe2O4 nanoparticles, 93% of MB-dye degradation is measured in 80 min, indicating excellent photocatalytic properties. Based on the as-synthesized NiFe2O4 nanoparticles’ observed properties, the effectiveness of MIFE as an environmentally friendly surfactant, and the low-cost dye-degradation prospects of green synthesized NiFe2O4 nanoparticles are affirmed.

Nickel-ferrite (NiFe 2 O 4) nanorods particles (NRP) was biosynthesised for the first time by the Rosemary Extract. The NRP was fully characterised, including the type, nanostructure and physicochemical properties of using XRD, HRTEM, FeSEM, XPS, FTIR and VSM. TEM confirmed rod-shaped nano-sized particles with average sizes ranging from 10 nm to 28 nm. The EDAX Analysis showed the presence of iron, nickel, oxygen, and carbon. XRD analysis confirmed the synthesis of NiFe 2 O 4 crystals. XPS curves showed photoelectron for iron, oxygen and nickel. EDS showed the atomic, weight percentages ratios of Ni(12%): Fe(24%) and: O(48) are close to the theoretical value (Ni: Fe:O ¼ 1:2:4), of bimetallic magnetic NiFe 2 O 4 NRP. NiFe 2 O 4 NRP had cytotoxicity effect on MCF-7 cells survival which suggests that NiFe 2 O 4 NRP can be used as a new class of anticancer agent in design novel cancer therapy research.

Nanotechnology is very important in developing sustainable technologies for the future. Increased demand for metal and metal oxide nanoparticles has led to their large‐scale production using conventional chemical methods with various toxic solvents. These techniques produce poisonous and harsh products that present a biological risk to the environment and have terrible effects on the life of microbes, plants, vertebrates, and invertebrates at different trophic levels. Thus eco‐friendly “green” synthesis methods have become necessary to synthesize nanoparticles using biological entities, such as plants and microorganisms. When compared to other methods, “green” synthesis is safer for human health and the environment. Plants, the main factory for the green synthesis of nanoparticles, have been used extensively for this purpose. This review, focuses on eco‐friendly synthesis to design spinel ferrite nanoparticles, particularly, using extracts from plant products that act not only as precursors but also as reductants and stabilizers during the synthesis process. The outstanding features of these nanoparticles allows for their promising applications in catalysis, lithium‐ion batteries, information storage, magnetic cores, ferrofluids, microwave, and medicine. This important review also highlights noteworthy recent developments related to the green synthesis of plant‐mediated magnetic spinel nanoparticles and their fundamental applications.
