The progress of ferrites and ferrites-based nanocomposites has become extensively popular in the field of photocatalytic wastewater treatment. This class of compound exhibit several fascinating properties related with their high stability, low cost, ease of functionalization, and biocompatibility. Ferrites carry outstanding magnetic behavior that helps in their easy recovery from the aqueous system thus reducing the cost. The morphology and various properties such as magnetic, absorption, optoelectronic of magnetic ferrites can be varied and optimize by applying different synthetic routes and reaction conditions. With this background we have briefly presented and reviewed the latest development in the field of photodegradation of aqueous pollutants using ferrites based heterojunction. Especially, the type-II, Z-scheme and S-scheme based heterojunction for enhanced pollutant degradation under the exposure of light are thoroughly describe. Ferrites have inherent potential in water remediation applications hence many examples were consider to impart valuable knowledge to the readers. Nevertheless, the large-scale utilization of these magnetic nanoparticles still needs to be explored. Therefore, the gaps, challenges and future prospective of ferrites nanoparticles are also explained to unveil the un-scrutinized standard of ferrites nanoparticles.

An effective heterojunction with robust charge separation and enormous degradation efficiency is the major task for photocatalysts preparation. In this manuscript, we have prepared the Fe 0.03 Ni 0.97 Co 2 O 4 loaded g-C 3 N 4 nanosheet by sol-gel assisted calcination method. The Fe dopant alters the electronic band structure of NiCo 2 O 4 and reduces the bandgap to 1.72 eV, which is beneficial for solar-light utilization. The addition of g-C 3 N 4 provides the large active sites for photocatalytic degradation under visible-light irradiation. Moreover, the nanocomposite exhibits high efficient charge separation behaviour than pure g-C 3 N 4 for degradation reaction. The synergistic interaction between the nanoparticles increases the MB (methylene blue) & Rh B (rhodamine B) degradation efficiency upto 99 % and 96 % in the presence of chemical oxidant respectively. Moreover, the heterojunction exhibits Z-scheme photo-Fenton like degradation behaviour with active radicals (superoxide (O 2 À * )/ hydroxyl (OH * )) production. Besides, the recycling experiment clearly revealed that heterojunction composite has high enough degradation stability towards organic pollutant degradation.

“…Thus, it is important to develop an adhesive-like material to remove the organic pollutants from water bodies to minimize pollution [11][12][13]. Many techniques have been used to remove phenol from wastewater such as photocatalytic degradation, membrane filtration, chemical oxidation, and solvent extraction [14][15][16][17][18][19][20][21]. Recently, Wang et al prepared 2D/2D γ-MnO 2 /rGO using rGO and KMnO 4 for the catalytic ozonation of 4-chlorophenol in the presence of PMS [22].…”

To enhance reusability and to maintain higher efficiency in degradation, Mn3O4/rGO nanocomposites were synthesized by a facile thermal treatment. Initially, Mn3O4 nanoparticles were prepared and analyzed by powder XRD and HR-SEM. The composition of manganese oxide was varied to obtain different nanocomposites. The Mn3O4 ions were found to be well anchored onto the rGO surface. The obtained samples were taken for the photodegradation studies with phenol as the pollutant. Under a dynamic mode, the absorption efficiency was found to be maximum for the MnsR0.75 sample for phenol.
