It has been found that the addition of 0.5wt.% potassium to a catalyst consisting of 8wt.% Ni supported on a MgO–ZrO₂ support prepared by co-precipitation improved both the activity and stability of this material for the dry reforming of methane. Increasing the content of potassium caused a decrease in the catalytic activity but the stabilities of the resultant catalysts were still higher than those for the undoped catalyst. The BET surface areas of the catalysts increased with potassium content.
