The invention provides a nano combustion catalyst. The nano combustion catalyst is prepared from the following raw materials: aluminium oxide, silicon dioxide, cerium oxide, ferric oxide and manganeseoxide with the weight ratio being (40-60):(20-30):(1-5):(10-30):(5-10), wherein cerium oxide is nano cerium oxide, ferric oxide is nano ferric oxide, and manganese oxide is nano manganese oxide. Theinvention also provides a preparation method of the nano combustion catalyst. The preparation method comprises the following steps of: weighing aluminium oxide, silicon dioxide, cerium oxide, ferric oxide and manganese oxide according the weight percent, and mixing with water to obtain preparation raw materials; placing the preparation raw materials into a ball mill for ball milling; adopting a forming process to prepare the ball-milled preparation raw materials into spheres or cylinders; placing in a roasting furnace for roasting, then taking out, and cooling to room temperature. The nano combustion catalyst provided
