Cobalt, nickel, and zinc nanosized spinel-type ferrites (MFe2O4, M: Co 2+ , Ni 2+ , and Zn 2+ ) were made by Arturo Adrián, et al. utilizing an original oil-in-water microemulsion process. These compounds, especially those created by microemulsion, have not been thoroughly examined for H2 production by the water-splitting mechanism. Pemartin et al. demonstrated the potential of oil-in-water microemulsion reactions as an eco-friendly alternative for synthesizing mixed oxide spinels with magnetic properties. By using the micro-emulsion process, Ca-Ni co-substituted samples of nanocrystalline spinel ferrites with the chemical formula Mg1xCaxNiyFe2yO4 (x=0.0-0.6, y=0.0-1.2) were created by Rajjab et al. and they were then annealed at 700°C for 7 hours. The improved magnetic properties of synthetic materials make them ideal for switching and high-frequency applications, while their reduced dielectric qualities make them ideal for high-frequency applications. La-doping Typical micro-emulsion approach used by Ketan A et al. to manufacture Ni-rich nano Ferro spinel compounds. Neodymium (Nd 3+ ), a rare earth element, and its impact on the characteristics of LiNi0.5NdxFe2xO4 spinel ferrites were covered by Zaheer Abbas, et al. These ferrites were produced using a simple microemulsion method. After employing a multi-microemulsion strategy, a reverse micelle method was used by Uskoković, V. et al. to create stoichiometric nanocrystalline nickel-zinc ferrites. The study by Misra et al. demonstrates the microemulsion technology's ability to synthesize a narrow size distribution of various nanocrystalline ferrites, including nickel and zinc ferrites.
