(57) [Summary] (Modified) [Purpose] When removing carbon monoxide in the air by oxidizing it to carbon dioxide, even if the air contains water, it is possible to recover efficiently at temperatures near room temperature. A method for oxidizing and removing carbon oxide is provided. [Composition] A catalyst used for oxidizing carbon monoxide, For example, a catalyst that is a composite oxide of Hopcalite or an oxide of manganese and an oxide of one or more elements selected from the group of copper, cobalt, nickel, iron, silver, vanadium, and chromium has a hydrophobic property. Is given. [Effect] It is possible to efficiently treat carbon monoxide in a water-containing gas. |
