Abstract
This study examines the effect of TiO₂ doping on the catalytic performance of copper ferrite (CuFe₂O₄) nanoparticles in degrading methyl green dye under visible light. Copper ferrite nanoparticles were synthesized and doped with varying TiO₂ concentrations. The catalysts were characterized using XRD, SEM, EDX, and BET surface area analysis. The TiO₂-doped copper ferrite catalysts showed significantly enhanced catalytic activity compared to undoped copper ferrite. The optimal doping concentration of 10 wt% TiO₂ achieved a degradation efficiency of 92 % for methyl green dye after 60 min of irradiation. The BET surface area increased with TiO₂ doping, contributing to the improved catalytic performance. Reusability tests over five cycles indicated a slight decrease in efficiency, attributed to the loss of active sites. These results indicate that TiO₂ doping effectively enhances the catalytic properties of copper ferrite, making it a viable option for environmental remediation.
