摘要：
A set of perovskite-type catalysts of general formula La0.8Sr0.2Co0.5M0.5O3 (M = Co, Ni, Cu) were prepared by alanine solution combustion method and used successfully for the methane combustion. The property of these materials were characterized by XRD, and TPR measurements. The effects of transition-metal ions on site B on structure and performance of the catalysts were studied. The result indicated that the structure and catalytic activities of the catalysts can remarkably affect by transition-metal ions on site B, the decrease of the electrons filled in d orbitals in the atom on site B is propitious to increase the catalytic activity for methane combustion, and the sequences of catalysts activities are La0.8Sr0.2CoO3 τ; Ce0.8Sr0.2CoO3 τ; Nd0.8Sr0.2CoO3.
