In this study, CCZY spinel ferrite nanoparticles were prepared using the citrate technique, showing promising properties for applications in data storage and water treatment, due to their unique characteristics such as high saturation magnetization and efficient dye removal capabilities.
Co0.5Cu0.25Zn0.25YxFe2-xO4; (0 <= x <= 0.1; step 0.02) (CCZY) spinel ferrites were prepared by citrate technique. The prepared CCZY samples have crystallite sizes ranging from 21 to 34 nm. The nanoscale nature of the samples was, also, established by HRTEM micrographs. Even though the substitution route here involves the replacement of magnetic ions Fe(3+)by a non-magnetic one Y-3, the magnetization of CCZY nanoparticles did not show a continual decrease as expected. The nanoferrite Co0.5Cu0.25Zn0.25Y0.06Fe1.94O4, has a moderate value of saturation magnetization 63.45 emu/g (decreased with 11.55% than the pristine sample) and higher coercivity 416.44 Oe (increased with 21.83% than the pristine sample), which may be a suitable candidate for data storage applications. All CCZY nanoferrite have direct optical band gap within the range 1.57 eV-1.50 eV; which doesn't introduce a regular behavior with Y/Fe substitution process. Distinctively, the MB dye removal shows an optimum value with the nanoferrite CCZY (0.1), which gives a degradation efficiency of 95% after 60 min only. The outstanding increase in catalytic performance of the nanoferrite CCZY (0.1) was correlated with the size factor and saturation magnetization. The desirability function approach enabled to distinguish the optimal material (CCZY (0.1)) with the superior catalytic performance; the smallest size and convenient magnetic properties. Hence, the nanoferrite Co0.5Cu0.25Zn0.25Y0.1Fe1.9O4 can be utilized efficaciously for water treatment, via the safe photocatalytic process; without sabotaging the environment.
