Iron oxides are old but gold. Stacks of review articles have been published with regard to sounding the magnificence of iron oxides for many applications. Nevertheless, no existing review papers discuss more specifics on how to fabricate nanometer-sized iron oxides, which, in fact, we can obtain them directly from natural sources and wastes via green technology. Direct synthesis of nanometer-sized iron oxides from natural sources and wastes could simply make them less expensive, and, of course, significantly decrease the energy requirement in the synthesis process, lower time synthesis consumption, and be environmentally benign. Here, we compile and synthesize all information on nanometer-sized iron oxides, starting from their phase diversity and their low-dimensional forms such as in zero-, one-, two-, and three-dimensional (0D, 1D, 2D, and 3D, respectively) shapes. Furthermore, the synthesis of nanometer-sized iron oxides from natural sources and waste materials via green synthesis is explained comprehensively, followed by the elucidation of the prospect and challenges of each synthesis method. Lastly, the recent applications and potential commercialization of nanometer-sized iron oxides synthesized from natural sources and waste materials from the point of view of green technology are also listed in this review article.

“…Iron oxide nanoparticles (IONPs), in particular, have found extensive utility in biological applications, spanning from the immobilization of proteins and enzymes to immunoassays, RNA and DNA purification, bioimaging, and environmental bioremediation (He et al 2017, Zhang et al 2014, Lee et al 2018, Wierzbinski et al 2018, Vanyorek et al 2019. Their oxidative stability, compatibility with non-aqueous systems, and low toxicity further underscore their significance (Malhotra et al 2020).…”

Iron oxide nanoparticles exhibit unique magnetic properties and possess a high surface-to-volume ratio, making them ideal candidates for the conjugation of substances, including enzymes. Laccase (EC 1.10.3.2), an oxidative enzyme with diverse applications, presents an opportunity for enhancing stability and reusability through innovative immobilization techniques, thus reducing overall process costs. In this study, we employed a direct binding procedure via carbodiimide activation to conjugate laccase onto iron oxide nanoparticles synthesized using thermal chemical coprecipitation. Stabilization of the nanoparticles was achieved using thioglycerol and polyvinyl chloride as capping agents. Characterization of the synthesized nanoparticles was conducted using UV-spectroscopy, Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and Energy dispersive X-ray spectroscopy (EDS). FTIR spectroscopy analysis confirmed successful laccase binding to magnetic nanoparticles, with binding efficiencies of 90.65% and 73.02% observed for thioglycerol and polyvinyl chloride capped iron oxide nanoparticles, respectively. Furthermore, the conjugated enzyme exhibited remarkable stability, retaining nearly 50% of its initial activity after 20 reuse cycles. This research demonstrates that immobilizing laccase onto iron oxide nanoparticles enhances its activity, stability, and reusability, with the potential for significant cost savings and expanded applications in various fields.

“…Possible supports with magnetic properties are: ferrites, chromium dioxide, magnetite, maghemite. They are also used in many separation operations, such as DNA purification [ 9 , 10 ], heavy metal ions binding [ 11 , 12 ], removal of organic contaminants from water [ 13 , 14 ], and even in the field of catalysis [ 15 , 16 , 17 , 18 ]. Weng and co-workers [ 19 ] converted nickel-laden electroplating slurry into NiFe 2 O 4 nanomaterial using sodium carbonate by a hydrothermal washing strategy.…”

2,4-diaminotoluene (TDA) is one of the most important polyurethane precursors produced in large quantities by the hydrogenation of 2,4-dinitrotoluene using catalysts. Any improvement during the catalysis reaction is therefore of significant importance. Separation of the catalysts by filtration is cumbersome and causes catalyst loss. To solve this problem, we have developed magnetizable, amine functionalized ferrite supported palladium catalysts. Cobalt ferrite (CoFe2O4-NH2), nickel ferrite (NiFe2O4-NH2), and cadmium ferrite (CdFe2O4-NH2) magnetic catalyst supports were produced by a simple coprecipitation/sonochemical method. The nanospheres formed contain only magnetic (spinel) phases and show catalytic activity even without noble metals (palladium, platinum, rhodium, etc.) during the hydrogenation of 2,4-dinitrotoluene, 63% (n/n) conversion is also possible. By decorating the supports with palladium, almost 100% TDA selectivity and yield were ensured by using Pd/CoFe2O4-NH2 and Pd/NiFe2O4-NH2 catalysts. These catalysts possess highly favorable properties for industrial applications, such as easy separation from the reaction medium without loss by means of a magnetic field, enhanced reusability, and good dispersibility in aqueous medium. Contrary to non-functionalized supports, no significant leaching of precious metals could be detected even after four cycles.
