In this study, the photocatalytic oxidation of CO was investigated. CuCr2O4 spinel was synthesized by the sol-gel method. For improving the performance of photocatalyst, it was added to supports such as zeolite (Si/Al) = 20 and TiO2 nanoparticles. The photocatalytic process was investigated in a tubular reactor and analyzed with Gas Chromatography. The response surface method was used to obtain the optimum catalysts for the carbon monoxide photocatalytic removal process. Predicted values of CO removal were found to be in agreement with experimental values for CuCr2O4/TiO2 and CuCr2O4/ZSM-5 (R-2 = 0.9546 and 0.9145, respectively). Optimization results showed that CuCr2O4/TiO2 enabled removal of 82% CO at the optimal condition: support loading ratio of 0.74 and calcination temperature of 697 degrees C. The catalyst properties were characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR), scanning electron microscopy (SEM), UV-vis diffuse reflectance spectroscopy (DRS), and Photoluminescence (PL) spectra methods. The optimum catalyst was applied on two types of white and pozzolanic cement and the practical efficiency was evaluated. The purpose of this project was to eliminate maximum CO in the shortest possible time.
