Abstract :Fe2O3-V2O5 mixed oxides were synthesized with solid-state dispersion insert ignore into journalissuearticles values(SSD); and coprecipitation methods. In addition, transition metal oxides such as CuO, NiO, and Co3O4 were successfully loaded on the synthesized catalyst insert ignore into journalissuearticles values(Fe2O3-V2O5); using the SSD method. The composite catalysts were inspected for their photocatalytic activities in degrading 2,4-dichlorophenol under UV light enforcement. The produced samples were analyzed using X-ray diffraction, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, diffuse reflectance spectroscopy, scanning electron microscopy, photoluminescence, and the Brunauer-Emmett-Teller method. The addition of transition metal oxides improved the photocatalytic activity of Fe2O3-V2O5 insert ignore into journalissuearticles values(SSD);. 1CuO wt% Fe2O3-V2O5 exhibited the highest percentage of 2,4-dichlorophenol degradation insert ignore into journalissuearticles values(100%); and the highest reaction rate insert ignore into journalissuearticles values(1.83 mg/L min); in 30 min. This finding is attributed to the distribution of CuO.
