[Display omitted] •Spinel FeCe2O4 catalyst on alumina foam studied for the propane dry reforming reaction.•FeCe2O4 catalyst to improve the productivity and enhance the resistance to deactivation of catalyst.•Propane conversion higher than 90% is achieved with negligible carbon.•Significant improvement of catalytic activity, high stability and inhibition of coke formation by FeCe2O4 catalyst compared to NiO–CeO2. Dry reforming of propane (DRP) with CO2 was examined over iron–ceria spinel (FeCe2O4) that was synthesized on mesoporous alumina foam by the sol–gel method. The FeCe2O4/Al-F catalyst exhibited significant catalytic activity for the DRP with propane and CO2 conversions of 93% and 76%, respectively. Moreover, the redox behavior of the spinel was found to greatly reduce the deposition of carbon, which could be attributed to the oxidation of surface carbon to CO via the interaction with FeCe2O4 lattice oxygen. The FeCe2O4/Al-F catalyst with good catalytic activity, long-term stability and coke resistance may be a promising candidate for the DRP.
