Prepared powders were calcined at 1350°C for 36h and 1450°C for 4h in air. These powders were then formed into a porous structure using sacrificial pore formation via oxidation of co-mixed graphite powder. These formed structures obtained were then characterized using thermogravimetric analysis (TGA), x-ray diffraction, high-temperature x-ray diffraction, scanning electron microscopy, and energy-dispersive x-ray spectroscopy. Brunauer-Emmett-Teller surface area analysis was performed on the most promising of the structures before being subjected to 50 thermal reduction-CO2 oxidation (redox) cycles using TGA. Together, these results indicate that CoFe2O4-8YSZ can provide a lower reduction temperature, maintain syngas production performance from cycle to cycle, and enhance utilization of the reactive material within the inert support in comparison to iron oxide only structures.
