In this research, a series of −yFeyO3−δ (y = –) was successfully synthesized by a solidstate reaction method and syngas production studies were performed using gas chromatography. Thermogravimetric analysis characterized the concentration of Fe3+, which gave a low H2/CO ratio over −yFeyO3−δ without the presence of molecular oxygen. All samples possessed a purely rhombohedral structure. The incorporation of more Fe increased the lattice parameter and changed XRD peaks of the La1− from sharp and single to double. |
