Abstract

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}$5 (SSD). 1CuO wt% Fe$_{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.
