▎ 摘　　要

NOVELTY - Removing contaminant involves using a material comprising an adsorption material for adsorption of the contaminant and a decomposition material for decomposition of the contaminant, where the adsorption material and the decomposition material are complexed with each other, and a contaminant decomposition onset temperature of the decomposition material is equal to or lower than a contaminant desorption onset temperature of the adsorption material. USE - Method for removing contaminant. ADVANTAGE - The method includes the generation of active oxygen may be additionally induced, so that the oxygen defect-inducing atom may serve to further improve a contaminant decomposition efficiency of the material for decomposition of a contaminant. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a filter for removing a contaminant, which includes the material, and a heating tool for transferring heat to the decomposition material in the material; and (2) a device for removing a contaminant, which includes filter for removing the contaminant, and filter comprising the material, and a heating tool for transferring heat to the decomposition material in the material. DESCRIPTION OF DRAWING(S) - The drawing shows the enlarged schematic view of an embodiment of a material for removing a contaminant and a filter for removing a contaminant. Contaminant. (10.)
