مستخلص: CuO-CeO 2 catalysts supported on material synthesized from red mud and rice husk ash (CuO-CeO 2 /ZRM) were prepared by co-impregnation method. The role of CeO 2 additive in the improvement of physicochemical properties and catalytic activity of CuO-CeO 2 /ZRM catalysts were emphasized. Several techniques, including Brunauer-Emmett-Teller Nitrogen physisorption measurements, X-ray powder diffraction, hydrogen temperature programed reduction, scanning electron microscopy and transmission electron microscopy (TEM) were used to investigate the properties of catalysts. Crystallite size calculated by Scherrer' equation was 17.4 - 21.8 nm. Modification of 5 wt% CuO/ZRM catalyst with CeO 2 had reduced the size of the nanoparticles leading to a significant enhancement of the catalytic activity in p-xylene deep oxidation at temperature range of 275 - 400 °C. The 5 wt% CuO/ZRM sample promoted by 3 wt% of nanoparticle CeO 2 with the average size of 17.5 nm and BET surface area of 31.3 m 2  g -1 exhibited the best activity for p-xylene deep oxidation. In this sample, the conversion of p-xylene reaches to 90% at 350 °C.
