Distinct pathway of multiferroic silver-decorated zinc ferrite nanocatalyst performance for Acinate insecticide...

The current study investigating the preparation and application of a Multiferroic nano-scale silver zinc ferrite substance (Ag_0.5Zn_0.5Fe₂O₄ nanocatalyst) has been established. Multiferroic silver zinc ferrite substance is prepared by co-precipitation technique as hybridized composite. This synethsized nanoparticles was characterized via X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM) as well as Scanning Electron Miscospopy (SEM). Such nanoparticles are used as a sustainable recyclable photo-Fenton's reagent precursor for treating insecticide in wastewater. The results revealed a high Acinate oxidation rate reached to 97% removal within 40 min of irradiance time. To increase the performance, the operating variables are optimized. pH 3.0 and 40 and 400 mg/L for Ag_0.5Zn_0.5Fe₂O₄ and hydrogen peroxide, respectively are identified as the optimum values. Also, kinetics and thermodynamic are evaluated and the reaction is subsequent the first-order kinetics model and exothermic and non-spontaneous in nature with a low energy barrier of 35.02 kJ/mol. The advantage of Ag_0.5Zn_0.5Fe₂O₄ catalyst is its sustainability since it recovered for multiple reuse with a high activity reached to 80% removal rate after six cyclic use compared to 97% of fresh catalyst use.
