Spinel ferrites demonstrate extensive applications in different areas, like electrodes for electrochemical devices, gas sensors, catalysts, and magnetic adsorbents environmentally important processes. However, defects the real spinel structure can change many physical chemical properties of ferrites. Although number a crystal lattice is small, their influence on vast majority could be really decisive. This review provides an overview structural characteristics compounds (e.g., CoFe

In awareness of industrial dye wastewater, carbon quantum dots (CQDs) and cobalt zinc ferrite (CZF) nanocomposites were synthesised for the making coated (CZF@CQDs) nanophotocatalyst using oxidative polymerization reaction. The results TEM, zeta potential value, FTIR confirm highly dispersed 1–4 nm particles with − 45.7 mV carboxylic functionalized surface CQDs. CZF@CQDs photocatalyst showed an average particle size ~ 15 according to SEM, XRD. a 1.20 eV band gap, which followed perfect visible light irradiation. TGA DTA revealed good thermal stability nanophotocatalyst. VSM was carried out, saturation magnetisations CZF 42.44 36.14 emu/g, respectively. A multipoint study determined BET-specific area be 149.87 m2/g. Under irradiation, final demonstrated remarkable efficiency (~ 95% within 25 min) in photocatalytic destruction Reactive Blue 222 (RB 222) Yellow 145 (RY 145) dyes, as well mechanical recyclability. Even after recycling degradation study, 82%, 7th cycles) predominantly maintained. effects several parameters also investigated, including initial concentration, CQD content, pH solution, reaction kinetics. Degradation data follow first-order rate (R2 > 0.93). Finally, simple low-cost synthesis approach, rapid degradation, outstanding CQD-coated should make it wastewater treatment.

Non-radical-based advanced oxidation processes, particularly those dominated by high-valent metals, have caught a great deal of attention because their exceptional degradation selectivity and robust interference resistance. This study reports the synthesis novel ferrite, designated as Co0.5Ni0.5Fe2O4, through solvothermal reaction, aimed at activating PMS for removal TCH from water. It was observed that calcination time played an important role in adjusting particle size catalyst, which subsequently increased its surface area. enlargement, turn, led to increase active sites, ultimately enhancing catalytic efficiency. Within Co0.5Ni0.5Fe2O4/PMS system, metals Fe(IV) Co(IV) became prominent primary species, with O21 serving secondary contributor. The activation mechanism thoroughly analyzed discussed. Co0.5Ni0.5Fe2O4 exhibited remarkable stability complex reaction environments during multiple recycling tests, maintaining efficiency exceeding 98%. not only increases awareness interaction between catalyst structure performance but also provides viable platform metal-dominated ferrite catalysts.

In this work, cobalt composite nano ferrites with chemical formula CoZr 0.05-x RE x Fe 1.95 O 4 (x = 0 and 0.025 Sm, Gd) were prepared using sol-gel synthesis method studied structural, optical magnetic properties of them. The Rietveld assessment XRD data validated the emergence a single-phase cubic spinel configuration for all compounds.
