Methane reforming with carbon dioxide to synthesis gas over Co-doped Ni-based magnetoplumbite catalysts Original Research Article

A series of Co-doped magnetoplumbite LaNixCo1−xAl11O19+δ catalysts were prepared and characterized by XRD, UV-DRS, TPR, and DTA–TG techniques. The experimental results showed that the series of catalysts possessed the pure magnetoplumbite structure and exhibited similar reduction stability values. At x≤0.375, the activities of the catalysts apparently increased with the increase of x-value, while over 0.375≤x≤1.0, the activities of the catalysts remained almost constant. Thus, it can be concluded that the content of Ni that is between 0.375≤x≤0.50, is suitable for the titled reaction.
