“…Due to the small particle size and active sites in the starting material, which can remove up to 98% of malachite green under UV irradiation, it exhibited good photocatalytic activity. Rahmani et al [ 70 ] dissolved metal nitrate precursors in a solution of Simbang Darah leaf extract. The hydrothermal synthesis was carried out and 10–80 nm spherical clusters of ZnFe 2 O 4 were prepared, which were able to degrade 99.66% of direct red 81 dye after 2 h of solar irradiation.…”

Zinc ferrite is a type of photocatalytic material with high physicochemical stability, narrow band gap, high carrier separation efficiency, high porosity, and paramagnetism, which makes it easy to recover. Thus, zinc ferrite is widely used as a photocatalyst in water treatment. In this paper, the preparation principles as well as the advantages and disadvantages of typical methods used to prepare zinc ferrite including hydrothermal, co-precipitation, sol-gel, and other novel methods such as biosynthesis have been summarized. Modification methods such as elemental doping, composite formation, and morphological modification have been highlighted. Using these modification methods, the catalytic activity of zinc ferrite toward the photocatalytic degradation of organic pollutants in water has been enhanced. Biosynthesis is regarded as a promising preparation method that uses biological materials instead of chemical materials to achieve the large-scale preparation of zinc ferrite using low cost, energy efficient, and environmentally friendly processes. Meanwhile, the combination of multiple modification techniques to enhance the photocatalytic performance of zinc ferrite will be an important research trend in the future.

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.

BACKGROUNDNowadays, the large amount of organic textile dyes being regularly consumed also releases hazardous residues into water sources. Nanotechnology can solve part of this problem by using nanoparticles as adsorbents and catalysts for the removal of dyes from water. The present study explored the facile and green synthesis of ZnFe2O4 nanoparticles using Chrysanthemum spp. flower‐mediated extract (ZFOB) as a reducing and capping agent for the removal of cationic malachite green (MG). ZFOB nanoparticles were characterized by various techniques, such as X‐ray diffraction, Fourier transform infrared spectroscopy, and scanning electron microscopy.RESULTSThe average particle size and Brunauer‐Emmett‐Teller (BET) surface area of ZFOB were found to be 60–80 nm and 10.9 m2/g, respectively. The pore size distribution indicated a characteristic of meso‐macropores of the biosynthesized ZFOB nanoparticles. The MG adsorption of the green ZFOB nanoparticles was investigated under batch mode through the effect of various parameters, including contact time (0–60 min), initial concentration (5–100 mg/L), pH (4.0–10.0), and adsorbent dosage (0.25–1.0 g/L). The adsorption process followed the Elovich kinetic model, () = 0.9992, while the adsorption behavior can be described by Koble‐Corrigan, () = 0.9915. Meanwhile, the maximum adsorption capacity was 121.2 mg/g from the Langmuir model at a contact time of 30 min, dosage of 0.5 g/L, and pH 7. Green ZFOB nanoparticles showed a good photocatalytic activity (80.4%) under solar light irradiation and they were able to be recycled up to four times while retaining their high stability.CONCLUSIONZnFe2O4 nanoparticles biosynthesized using Chrysanthemum spp. flower extract can be a good adsorbent and photocatalyst for the removal of MG dye. © 2022 Society of Chemical Industry (SCI).
