“…The gel was dried at 120 °C before being burned into a loose gigantic powder by self-propagating combustion. The gigantic powder was ground with an agate motor and pestle, and the fine powder was calcined at 750 °C [51]. Dhiman et al fabricated Mg 0.5−x Cu x Zn 0.5 Fe 2 O 4 (x = 0, 0.01 & 0.02) by solution combustion method.…”

Nano ferrites have piqued interest owing to their numerous uses in biomedical, wastewater remediation, and electronic devices. This chapter is primarily concerned with the various fabrication techniques for ferrite nanoparticles. This chapter presents various methods used for ferrites preparation with distinctive examples, their advantages as well as limitations in detail. The fabrication techniques used to achieve ferrites nanoparticles of various structures and morphologies, such as hydrothermal, microemulsion, solvothermal, solution combustion, microwave, chemical vapor deposition, sol-gel, chemical bath deposition, or wet chemical synthesis, sonochemical, thermal decomposition, and electrochemical methods, are briefly described. This chapter summarizes the recent work on the influence of synthesis techniques on the properties of ferrites in nanoform. Ferrites belong to the materials which are a potential candidate for widely spread applications. Keywords Ferrites • Nano materials • Synthesis techniques 1 IntroductionThe three major targets of magnetic nanomaterials are synthesis, knowledge of novel advanced materials, and relationships between them. Nanomaterials are those materials whose particle size lies between the range of 10-100 nm in at least one or more dimensions, as defined by their nanometric equivalents. A large number of atoms are present at or near the surface of particles at this length scale, giving the materials their specific properties. Nanomaterials have a high surface-to-volume ratio which

“…Colours are distinguished as most noteworthy chemical contaminants that cause wastewater contamination [195,196,197,198]. There has been developing exploration interests on photocatalytic decomposition using magnetic nanoparticles for environmental remediation because of the capability of these materials for enormous-scope application and compatibility with current innovations [199,200,201]. Magnetic ferrites and spinel structure have a restricted band gap ( ̴ 1.9eV) and that's why they are able for the engrossing visible light [202].…”

Many researchers are interested in investigating ceramic materials because of the potential for their use in nanotechnology. Spinel ferrites are a diverse group of materials with many applications. Electronic devices such as inductors, power, information storage, microwave, and induction tuners are only a few examples. As ferrite materials exhibit super-paramagnetic activity, their potential for biological applications such as drug delivery, hyperthermia, and resonance magnetic imaging. As a result, super-paramagnetism is a highly desirable property in spinel ferrites. Due to the size dependence, the methodologies used to synthesis of these materials have emerged as a critical step in achieving the desired properties. Many synthesis strategies have been developed in this regard such as sol-gel, co-precipitation, solid-state, solution combustion method and so on. As a result, this study provides a historical overview of spinel ferrites, as well as key principles for comprehending their various characterization techniques and properties. Recent developments in the synthesis and applications of spinel ferrites are also discussed.

The present review highlights the different types of nano ferrites and their surface modified composites as an alternative adsorbent in waste water treatment. In this review, the recent progresses and potential applications of SFNPs/SFNCs for the removal of organic and inorganic contaminants through adsorption routes are critically reviewed. There are number of water purification techniques but the adsorption is one of the simplest, effective and economical method for wastewater purification. Adsorption isotherm models, kinetic models, thermodynamic parameters and adsorption mechanism have also been discussed. The present article lists different type of adsorbents and reviews state-of-the-art of the removal of different pollutants from water. The efforts have been made to discuss the sources of contamination and toxicities of pollutants. The possible techniques of recovery and reuse, toxicity, research gaps and the future perspective of SFNPs are also discussed in brief. Based on this review, it is possible to conclude that SFNPs and their derivative composites have unlimited capacity in addressing array of problems encountered in water and wastewater treatment. The present study highlights the future areas of research for waste water treatment.
