Abstract

An embodiment of the present invention provides a noble gas hydride having the following formula 1: Ng n H m . In formula 1, Ng represents a noble gas atom, n represents an integer from 1-8, and m represents an integer from 1-46.

First claim

The invention claimed is:

1. A noble gas hydride selected from the group consisting of:
HeH m where m represents an integer of from 1 to 4,
NeH m where m represents an integer of 1 or 2, and
ArH m where m represents an integer of from 1 to 4.

2. A fuel or a noble gas hydride releasing material for releasing a noble gas hydride according to claim 1 .

3. A method for producing a noble gas hydride according to claim 1 , comprising:
(a) bringing a surface of a metal or a metal oxide into contact with a noble gas to perform at least one of adsorption of noble gas atoms to the surface or occlusion of noble gas atoms into an interior of the metal or the metal oxide, and
(b) bringing the noble gas atoms present at at least one of the surface or the interior into contact with hydrogen atoms under a temperature condition of from 50 K to 298 K;
(c) bringing a metal or a metal oxide into contact with a hydrogen-containing gas under a temperature condition of from 50 K to 298 K to allow hydrogen atoms to be present at at least one of a surface or an interior of the metal or the metal oxide, and
(d) bringing the hydrogen atoms present at the metal or the metal oxide into contact with a noble gas; or
(e) supplying both a hydrogen-containing gas and a noble gas to a surface of a metal or a metal oxide; and
(f) bringing hydrogen atoms and noble gas atoms into contact on the surface of the metal or the metal oxide under a temperature condition of from 50 K to 298 K.

4. The method for producing a noble gas hydride according to claim 3 , wherein, in (b), the hydrogen atoms are produced by bringing the metal or the metal oxide into contact with a hydrogen-containing gas.

5. The method for producing a noble gas hydride according to claim 3 , wherein the metal or a metal of the metal oxide comprises at least one of nickel, copper, or palladium.

6. The method for producing a noble gas hydride according to claim 3 , wherein the noble gas atom is helium, neon, argon, krypton, or xenon.

7. The method for producing a noble gas hydride according to claim 3 , comprising heating the metal or the metal oxide before or after contact between noble gas atoms or a noble gas and hydrogen atoms, or simultaneously with contact between noble gas atoms or a noble gas and hydrogen atoms.

8. The noble gas hydride releasing material according to claim 2 , which releases a noble gas hydride by temperature elevation.

9. The noble gas hydride releasing material according to claim 8 , wherein the material is a metal or a metal oxide, and the metal or a metal of the metal oxide comprises at least one of nickel, or palladium.
