Preparation of La₀․₉₅Ce₀․₀₅CoO₃ with large surface area

Abstract

202-205The perovskite-type complex oxides, La₀․₉₅Ce₀․₀₅CoO₃, have been prepared by glycine polyacrylamide sol-gel combustion method, glycine sol-gel method and solid state reaction method. These oxides have been used successfully for combustion of methane. The La₀․₉₅Ce₀․₀₅CoO₃ samples have been investigated by XRD, BET, O₂-TPD and H₂-TPR. The effect of preparation method on the structure and performance of the catalysts has been studied. La₀․₉₅Ce₀․₀₅CoO₃ prepared by glycine polyacrylamide sol-gel combustion method shows the highest catalytic activity for combustion of methane
