摘要：

Rare earth perovskite-type oxides La2CuNiO6 and LaNiO3 were prepared by a sol-gel method and investigated as catalysts for the combustion of methane. The obtained powders were characterized by XRD, H-2-TPR, XPS and M techniques. XRD data shows that both La2CuNiO6 and LaNiO3 formed single-phase perovskite-type oxides. The experimental results show that the catalytic activity of La2CuNiO6 was much higher than that of LaNiO3 because of the different structure and surface properties. This study points out a potential way to develop more active double perovskite-type catalysts for the combustion of methane. (C) 2012 Elsevier B.V. All rights reserved.
