Under 180 mins of exposure to sunshine, the produced NPs' photocatalytic activity showed maximal degradation rates of 90%, 94%, and 98%, respectively. Behura, R. et al. effectively synthesized CoFe2O4 NPs by using iron recovered from waste iron ore tailings and cobalt recovered from wasted lithium-ion batteries. Subsequently, they were characterized and used for photo/sonocatalytic degradation of CR. Kaur, P. et al. developed a novel hexagonal ferrite-based coreshell-shell nanostructure, namely SrFe@Dop@M, for the combined electrochemical detection and photocatalytic degradation of medical drugs. M represents the elements Cr, Mn, Fe, Co, Ni, Cu, and Zn. The degradation of levofloxacin and SMX was assessed using a comparative photocatalytic assessment of SrFe, SrFe@Dop, and SrFe@Dop@M. Dhiman et al. observed the synthesis of Mg-substituted Zn nano-ferrite (Zn1-xMgxFe2O4) with varying levels of Mg. The purpose of this synthesis was to investigate its effectiveness in degrading sulfadiazine. The objective of the project is to create cost-effective photocatalysts that are solar-active and tunable, to efficiently degrade and mineralize pharmaceutical pollutants using photochemical processes. Makofane, A. et al. used an extract derived from the Monsonia burkeana plant to synthesize ZnFe2O4 NPs. The optimal conditions for achieving a 99.8% elimination of MB were a pH of 12, a reaction time of 45 minutes, and a catalyst dose of 25 mg. The ability of the ZnFe2O4 NPs to be easily separated and recycled, as well as their continued effectiveness even after five reuses, demonstrate the material's great stability. The ROS tests also showed that the key elements causing MB to deteriorate are electrons. Sulfisoxazole in water degraded by 67% when the photocatalytic efficiency of the sulfonamide antibiotic was tested. This study has demonstrated that these materials can be utilised to target water contaminated by textiles and drugs. CoFe2O4 NPs that were synthesized by Balakrishnan, et al. were produced using the Coprecipitation method. Analyses were conducted on the degradation of ampicillin caused by the cooperative action of CoFe2O4 and PMS NPs. The estimated optimisation of the impacting parameters during deterioration.
