An object of the present invention is to provide a catalyst useful for decomposing and removing pollutants such as VOC, which can exhibit high catalytic activity at room temperature without requiring light irradiation or a heat source. A catalyst containing manganese oxide, wherein the ratio of Mn 3+ to Mn 4+ (Mn 3+ / Mn 4+ ) of the manganese oxide is 0.970 or more. In order to improve the catalytic activity at room temperature, etc., in addition to manganese oxide, at least one cocatalyst selected from the group consisting of cerium, cerium oxide, iron, iron oxide, aluminum and aluminum oxide is further added. May be contained. [Selection diagram] Fig. 1 |
