Example Embodiment
[0037] Example 1
[0038] A catalyst for the purification of formaldehyde at room temperature. The catalyst is composed of a porous inorganic oxide and a transition metal active component supported on the porous inorganic oxide and an auxiliary agent. The porous inorganic oxide is ceria, which is Surface area is 10m 2 / g, the particle size is 30nm, the active component is manganese-iridium composite oxide, the molar ratio of manganese to iridium is 0.03, based on the weight of the catalyst as 100%, the transition metal active component is based on the weight of the transition metal element, The weight percentage of the transition metal active component is 5%, the auxiliary agent is barium oxide, and the auxiliary agent content is 8%.
