Metal oxide catalysts Compared to zeolite catalysts, metal oxide catalysts have better thermal stability and hydrothermal stability so as to get the attention of people, but the single metal oxide catalysts are unstable at high temperatures,and the catalytic activity are low.The catalytic activity of composite metal oxides can be improved if we take some measures such as stabilization of some active components, structure control and adjustment.
