The perovskite oxide, LaFeO3, was synthesized by different preparation methods, i.e., the calcination of co-precipitated precursors [La(Ag)–Fe–CO3 and La–Fe–CO3] and a mixture of La2O3 and Fe2O3 (La–Fe–O). By using the solution of Ag, the formation temperature (600°C) of the LaFeO3 single phase obtained by the calcining of La(Ag)–Fe–CO3 was about 500°C lower than that of La–Fe–CO3. The formation temperature of the LaFeO3 single phase of La–Fe–O was 1100°C as well as that of La–Fe–CO3. Their carbon oxidations were investigated by DSC (differential scanning calorimetry) measurements. The DSC exothermic peak of La0.9Ag0.1FeOα obtained by the calcining of La(Ag)–Fe–CO3 at 700°C occurred at 409°C and showed a higher carbon oxidation activity when compared to LaFeO3 (477 and 562°C) obtained by the calcining of La–Fe–CO3 and La–Fe–O at 1100°C. The carbon oxidation activation energies observed for the non-catalyzed and catalyzed reactions (mixture of La0.9Ag0.1FeOα) were 160 and 130 kJ·mol−1, respectively.
