The La2BMnO6 (B=Co, Ni) double perovskite oxides were synthesized using the sol-gel method and deposited on MgO support (loading = 10, 20, and 30 wt. %) using a mechanical mixing method by an ultrasonic device. The elaborated samples were investigated for application in propane deep oxidation. The catalytic performance of these catalysts was analyzed by a variety of characterization techniques such as XRD, SEM, FTIR, TEM, and H2-TPR. Ni-containing catalysts were found to have superior catalytic activity than the sample containing Co. The lowest catalytic activity belonged to the cobalt-containing double perovskite with 10 wt.% loading on MgO support, while the highest conversion was related to the 20La2NiMnO6/MgO composite oxide with T90 = 434 °C. The support showed a positive impact on the performance of the catalysts. Deposition of a certain amount of perovskite oxides on the support boosted the specific surface area of the catalyst and, therefore, combined with improved reducibility, improved propane catalytic degradation. Highlights The deposition of La2BMnO6 (B = Co, Ni) double perovskite oxides on MgO support has been successfully accomplished by a facile method. Deposition of the perovskite on the MgO support led to higher specific surface area, and higher reducibility of the supported catalyst. Certain loading of the perovskite oxide on MgO support is conducive to a superior catalytic combustion activity as compared with unsupported one. }, number={2}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, author={Roozbahani, Hamidreza and Maghsoodi, Sarah and Raei, Behrouz and Kootenaei, Amirhossein Shahbazi and Azizi, Zoha}, year={2023}, month={Nov.}, keywords={Catalytic combustion, Composite oxide, Double perovskite oxide, Propane, Support} }
