? 2022 Elsevier B.V.The effect of variable O2 concentrations (5%, 10%, 15%, and 21%) in the injection mixing gas was examined on the properties of MgO/MgAl2O4 nanocatalysts created with solution combustion method for biofuel production. The results of XRD, FESEM, TEM, EDX, BET, FTIR and TG/DTG manifested that among all above-mentioned O2 contents injected into synthesis pot, the 21% O2 sample provides the possibility for the fuel to undergo complete combustion leading to superior characteristics of this nanocatalyst including better dispersion of MgO on the support, well-formed crystals, higher surface area with large pore volume and higher catalytic performance during transformation of vegetable fats to biofuel (98.2%) compared to the other samples without any gas injection or with lower oxygen contents. The conversion of air injected sample indicated only 2.8% connversion loss after five rounds of use, indicative of a mesoporous catalyst with still an acceptable conversion rate (93.8%) for biodiesel production.
