It has been found that it has the characteristics to capture. That is, since the size of the C12A7 cage is about 4 mm and the size of the imide anion is about 3 mm, the imide anion is considered to be taken into the cage by the treatment of the present invention.
- a stable imide anion-containing compound can be synthesized for the first time in air or in a solvent, and a practical inorganic imide compound can be provided.
- the maximum NH content of the mayenite type compound into which the imide anion of the present invention is injected corresponds to about 0.26 wt%, and the NH concentration corresponds to about 2.7 ⁇ 10 20 cm ⁇ 3 .

- imide anions were not taken in even when calcium oxide, alumina, or composite oxides thereof having no cage structure were similarly immersed in liquefied ammonia and heat-treated.

From the above results, it was found that an imide anion containing NH 2 ⁇ having a concentration of 1 ⁇ 10 18 cm ⁇ 3 or more and having chemical stability can be injected into the mayenite type compound according to the present invention.

- the C12A7 porous body and solid sintered body containing conduction electrons may be heated in a reducing atmosphere with Ca, CaH 2 , Ti, and the like after forming a C12A7 raw material powder having a chemical equivalent composition.
- a substrate other than the thin film and the solid single crystal can produce a C12A7 substrate containing conduction electrons directly from the raw material without going through the production of a C12A7 substrate containing no conduction electrons.
- a C12A7 base material containing a hydrogen anion can be synthesized in the form of a powder, a porous body, or a solid sintered body by heating in a hydrogen stream or a reducing atmosphere with Ca or the like.
- the C12A7 thin film containing conduction electrons is formed on a substrate such as MgO, Y 3 Al 5 O 12 by a pulse laser deposition (PLD) method, sputtering method, plasma spraying method, etc. using a solid sintered body of C12A7 as a target.

- conduction electrons may be missing from the surface portion of the base material regardless of whether it is a powder, a porous body, a solid sintered body, a thin film, or a solid single crystal.
- heating is performed at 900 ° C. or higher to less than the melting point (1250 ° C.) of the compound in a vacuum, an inert gas or a reducing atmosphere, and conductive electrons of 1 ⁇ 10 15 cm ⁇ 3 or higher are transferred to the outermost surface of the substrate. Can be included.
- ⁇ Step of including an imide anion in the mayenite type compound a high-pressure vessel such as an ammonothermal apparatus is used, and the liquefied ammonia is in the range of 450 to 700 ° C., more preferably 450 to 650. What is necessary is just to immerse in the range of ° C. When the immersion treatment temperature is 400 ° C. or lower, no imide anion is injected into the mayenite type compound. Moreover, since the decomposition reaction of liquid ammonia advances at the temperature exceeding 700 degreeC, it is unpreferable. *
- the concentration of mayenite in the liquid ammonia is 0.05 to 50% by weight, preferably 0.5 to 20% by weight, more preferably 1 to 10% by weight with respect to the ammonia. If the concentration is less than 0.05% by weight, imide ions are efficiently introduced into the cage, but this is not preferable in terms of efficiency. On the other hand, if the concentration exceeds 50% by weight, it is not preferable because it takes a long time to introduce imide ions.
- the treatment time is not generally determined by the conditions such as the treatment temperature and the mayenite concentration in the liquid ammonia, but it may be at least 1 minute at a predetermined temperature.
- Imide anion injection is considered to proceed as follows.
- ammonia reacts with oxygen ions (O 2- ) or electrons (e-) included in the skeleton of the mayenite type compound to give an amide anion.
- the amide anion reacts with the oxygen ion (O 2- ) or electron (e-) included in the skeleton to give an imide anion, and the oxygen ion (O 2 -) Or electrons (e-) are replaced by imide anions. Since the reaction pressure is about 500 times higher than that in the past gas phase ammonia treatment, it is considered that the reaction proceeds to the reaction for generating the imide anion of Formula 4 and Formula 5.
- Nano-inclusion with nanoporous materials such as organometallic complexes, supramolecules, and zeolites is effective for stabilizing and storing unstable chemical species, but a method for stably including imide compounds has not been known. And for the first time, we succeeded in inclusion of active imide anions with mayenite compounds. This means that the active N1 species (nitrogenated organic reaction reagent capable of generating C—N bonds) has been successfully stored.
- active imide anions with mayenite compounds. This means that the active N1 species (nitrogenated organic reaction reagent capable of generating C—N bonds) has been successfully stored.
- the mayenite type compound injected with the imide anion of the present invention can be applied to, for example, primary amine synthesis by hydroamination of an olefin having an unsaturated bond.
- the produced amine has high nucleophilicity, and sequential alkylation proceeds and a primary amine cannot be obtained.
- a selective reaction can be realized because an imide anion can be selectively reacted with a nucleophilic moiety, for example, a double bond.
- the characteristic of releasing ammonia at a high temperature is a characteristic not found in conventional materials. This means that it can be used for a reduction reaction at a high temperature. For example, it can act as a promoter for a catalytic reaction such as NOx reduction. *
