Summary: In this study, LaxNi0.5Co0.5Fe2-xO4 nanoparticles were used as catalysts for Methylene Blue degradation. The nanoparticles were produced using the citrate-aided sol-gel auto-combustion method and exhibited homogeneous size distribution. The structural and optical characteristics of the nanoferrites were analyzed using X-ray diffraction and UV-visible reflectance spectroscopy respectively. Morphological and compositional studies were conducted using FESEM and EDX spectra, while BET analysis was used to determine the surface area. Raman Spectroscopy was employed to estimate the vibration parameters. The most efficient catalyst, La0.06Ni0.5Co0.5Fe1.94O4, achieved a 98.69% efficiency in 140 minutes. The use of La3+ substituted Ni0.5Co0.5Fe2O4 nanoferrites as catalysts offers advantages such as high recycling capability, stability, and simplicity of separation using an external magnet.

Summary: This study investigates the influence of structural parameters of Fe-TiO2 catalysts on the performance of HPFO for wastewater treatment. Optimized Fe-TiO2 catalysts with iron lattice doping, well-dispersed ultrasmall alpha-Fe2O3 nanoparticles, appropriate anatase/rutile ratios, and abundant oxygen vacancy sites show superior performance in degrading methylene blue, attributed to the synergistic effect of anatase-rutile-Fe2O3 heterojunction, ultrasmall alpha-Fe2O3 nanoparticles, and oxygen vacancy sites.

Summary: The catalytic behavior of lanthanide-doped magnesium ferrites in the degradation of Methylene Blue using the Fenton process was studied. The doped samples showed an increase in crystalline structure parameters and crystallite size, with a significant decrease in catalytic activity at higher temperatures. Under UV irradiation, lanthanide-doped catalysts exhibited varying levels of efficiency, with the most active ferrites achieving up to 99% MB degradation in both visible-light and UV-driven Fenton processes.
