以下に本発明の実施例を説明する．
まず，触媒の一例について述べる。[Detailed Description of the Invention] [Field of Industrial Application] The present invention mainly relates to a deodorizing method that uses near-infrared rays to oxidize and decompose odors having functional groups at the molecular terminals, such as aldehydes and mercaptans. Regarding. [Prior Art] It is known that oxidation reaction deodorization is suitable for deodorizing the odors of aldehydes, mercabutane, etc. However, since it is usually exposed to air, that is, oxygen, and is constantly exposed to an oxidizing atmosphere, the purpose cannot be achieved unless auxiliary means such as high temperatures and catalysts are used for the oxidation reaction. Therefore, combustion methods using platinum catalysts and direct combustion methods without catalysts are known. [Problems to be Solved by the Invention] In the catalytic combustion method, the target gas contains a large amount of combustible components, and the heating of the catalyst is assisted by the reaction heat due to oxidation, or the direct combustion method without catalyst has self-combustibility. It requires a high concentration of flammable material that can be maintained. On the other hand, the air that is subject to odors contains a very small amount of odorous components in a large amount of air, and cannot be expected to exhibit self-combustibility or reaction heat. Therefore, maintaining high temperatures requires enormous energy costs and is not realistically possible. In view of the above circumstances, it is an object of the present invention to provide an economical deodorizing method that uses an inexpensive catalyst and does not require energy costs. [Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides an oxide that produces red color by electron beam excitation and supplies singlet oxygen, an oxidation catalyst, a photothermal ray absorber, and an oxide ion conductor. A mixture support made of It has a structure in which the photothermal ray absorber is graphite, and the oxide ion conductor is ytterbium oxide. [Function] In the present invention, red light is irradiated onto a mixture support consisting of an oxide that produces red color by electron beam excitation, an oxidation catalyst, a light absorber, and an oxygen ion conductor, and an odor gas is sprayed onto the irradiated surface. deodorization is performed. In other words, red color is produced by electron beam excitation, oxygen in the air becomes a singlet state due to the action of oxides, oxygen ion conductors coexist, oxidative decomposition of odors is effectively carried out, and the light absorber is elevated. The heat effect works synergistically to enhance the deodorizing effect, and it does not require expensive catalysts such as platinum catalysts, nor does it require a large amount of energy to maintain high temperatures. [Example] Examples of the present invention will be described below. First, an example of a catalyst will be described.

〔発明の効果〕Yttrium oxide 25g Ytterbium oxide 5g Europium oxide 1g Copper(1) oxide 20. A mixed powder of 20 g of copper(II) oxide, 25 g of graphite, and 25 g of calcined gypsum is prepared. The yttrium oxide produces a red color when excited by an electron beam and supplies singlet oxygen, the copper oxide is a conventionally used catalyst for oxidation reactions, and the graphite heats up by absorbing light. They are mixed to obtain an effect. In addition, ytterbium oxide and europium oxide exhibit high reactivity with air as oxygen ion conductors and red light emitting auxiliaries. In the present invention, the mixed powder is used supported on a solid support. For example, a wet paste of gypsum is applied onto a solid support, and while the paste is wet, the mixed powder is sprinkled on the paste to fix it, and after being left overnight, it is used for deodorization. In the present invention, we focused on singlet oxygen, which is highly reactive among active oxygen species, has a short lifespan, and poses no danger to the human body, and sought air as a source of this singlet oxygen. Furthermore, the near-infrared emission spectrum of singlet oxygen is approximately 1
．． It has a peak at 27lm and uses a red light as the excitation source. Next, the actual deodorizing method of the present invention will be explained. In the present invention, the surface of the mixed powder fixed on the solid support is irradiated with red light, and the odor is gently sprayed onto the irradiated surface to perform deodorization. As a result, oxidative decomposition of odors is promoted and effective deodorization is achieved. The actual measured values of the deodorizing effect of the present invention are as follows, and its effectiveness has been confirmed. The present invention, 0.
