Enhancing the magnetization, dielectric loss and photocatalytic activity of Co–Cu ferrite nanoparticles via the substitution of rare earth ions

This study reports the impact of lanthanum (La) substituted Co–Cu ferrite nanoparticles on rhodamine (RhB) dye disposal. Moreover, a complete investigation for structural, magnetic and optical properties Co0.5Cu0.5LaxFe2-xO4 (CCL) nanoferrites was executed. These nanocrystals were synthesized via combustion approach with peculiar lattice parameter behavior; which discussed through three hypotheses. The scanning transmission electron microscope - energy dispersive X-ray analysis (STEM-EDX) micrographs some selective samples confirm nanocrystalline nature presence all constituents’ chemical elements CCL nanoferrites. saturation magnetization tuned La3+ ions substitution. Contrary to expected results, anisotropy constant introduced decrement behavior La/Fe substitution process. microwave frequency (?M) values are in range 11.87–9.46 GHz. band gap has red shift followed by blue one. Through photodegradation testing, we explicate RhB degradation mechanisms over our nanoferrite Co0.5Cu0.5La0.15Fe1.85O4 moderate magnetization, highest coercivity, lowest loss, is suitable candidate data recording applications, furthermore can be utilized as photocatalyst effluents removal efficiency 94.50% at 180 min solar radiation.
