- 摘要：
PROBLEM TO BE SOLVED: To provide a catalyst for efficiently oxidizing indoor formaldehyde of low-concentration at comparative low temperature to completely oxidize the formaldehyde into carbon dioxide and water and remove the formaldehyde and to provide a method of manufacturing the catalyst.
SOLUTION: The catalyst for oxidizing formaldehyde includes a manganese-cerium uniformly/densely-mixed oxide as a catalyst A component and at least one metallic element selected from elements belonging to group 8 to group 11 of the periodic table as a catalyst B component. The catalyst A component is the manganese-cerium uniformly/densely-mixed oxide which has an X-ray diffraction peak corresponding to the fluorite structure of cerium dioxide as a main peak and contains manganese of 10-60 mass% in terms of manganese dioxide. The catalyst for oxidizing formaldehyde can be manufactured by using inexpensive raw materials, a simple manufacturing facility and a simple manufacturing method and can make formaldehyde be oxidized completely at comparably low temperature without using a noble metal and indoor air be cleaned.
