Carbon monoxide is one of the main air pollutants, mainly produced from the incomplete combustion of fossil fuels.  This study aims to oxidize carbon monoxide by copper oxide nanoparticles immobilized on zeolite13X substrate. The present investigation was conducted to determine the effect of carbon monoxide concentration parameters (in the range of 200-1400 ppm) and reaction temperature (in the range of 100-500 °C) on the efficiency of carbon monoxide conversion by CuO/Zeolite 13X nanocatalyst. The design of the experiment and the determination of the number of experiments were analyzed using the central composite design method, and the statistical test of analysis of variance was done using the response surface method. Also, the structural and morphological characteristics of the nanocatalyst were investigated using BET, BJH, FE-SEM, EDX, and XRF tests. The results show that CuO/Zeolite 13X nanocatalyst efficiently oxidizes carbon monoxide. The highest conversion efficiency of 82.6% was obtained at a temperature of 400 °C and a carbon monoxide concentration of 500 ppm as the optimal conditions. According to the EDX test results, copper oxide nanoparticles with a weight percentage of 5.9% were loaded on the Zeolite 13X substrate. Design Expert11 software reduced the cubic model with an R2 coefficient of 0.98.
