Fe 2 O 3 -V 2 O 5 mixed oxides were synthesized with solid-state dispersion (SSD) and coprecipitation methods. In addition, transition metal oxides such as CuO, NiO, and CO 3 O 4 were successfully loaded on the synthesized catalyst (Fe 2 O 3 -V 2 O 5 ) 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 Fe 2 O 3 -V 2 O 5 (SSD). 1CuO wt% Fe 2 O 3 -V 2 O 5 exhibited the highest percentage of 2,4-dichlorophenol degradation (100%) and the highest reaction rate (1.83 mg/L min) in 30 min. This finding is attributed to the distribution of CuO.
