Carbon dioxide reforming of methane was investigated over LaNi1-xCrxO3 perovskite catalysts which were prepared by the malic acid method. The respective perovskite catalysts were a single phase of perovskite oxide without impurity phases. Their reduction behavior was characterized by temperature programmed reduction. In the LaNi1-xCrxO3 perovskite catalysts, the catalytic activities were closely related to the reduction behavior of the catalysts, and the partial substitution of Cr to the B-site of perovskite catalysts promoted stability against reduction. When the x values were lower than 0.4, the LaNi1-xCrxO3 perovskite catalysts were decomposed to La2O3 and Ni and the decomposition of perovskite structure led to large coke deposition. When the x values were higher than 0.4, the LaNi1-xCrxO3 perovskite catalysts showed reduced catalytic activity but became stable to reduction and coke formation in the reforming reaction.
