Abstract A catalyst for simultaneously removing nitrogen oxide, sulfur oxide and carbon monoxide from flue gas is formed from complex oxide of magnesium, aluminium,at least one transition metal element and at least one rare-earth metal element. Said catalyst is made up by using mixture of laminate materials which possess hydrotalcite structure and contain Mg, Al and transition metal element and rare earth hydrated oxide through the roasting process. Said catlyst can simultanously remove nitrogen oxide, sulfur oxide and carbon monoxide from flue gas, and possesses excellent water thermal stability.
