First claim
Opening claim text (preview).
The invention claimed is: 1. A transition metal-supported intermetallic compound comprising a transition metal M supported on an intermetallic compound represented by formula (1): RTX (1) wherein R represents a lanthanoid element, T represents a transition metal in period 4 or period 5 in the periodic table, and X represents Si, Al or Ge. 2. An activator for hydrogenation reaction, comprising the transition metal-supported intermetallic compound according to claim 1 . 3. A method for using the transition metal-supported intermetallic compound according to claim 1 , comprising contacting the intermetallic compound with hydrogen to activate a bond in a hydrogen molecule. 4. A catalyst comprising the transition metal-supported intermetallic compound according to claim 1 . 5. The catalyst according to claim 4 , wherein the catalyst is a catalyst for ammonia synthesis. 6. A transition metal-supported complex comprising a transition metal M supported on an intermetallic compound-hydrogen complex represented by formula (2), wherein the intermetallic compound is capable of storing and releasing hydrogen reversibly and the complex is capable of releasing hydrogen at 400° C. or less: RTX· a H (2) wherein R represents a lanthanoid element, T represents a transition metal in period 4 or period 5 in the periodic table, X represents Si, Al or Ge and a represents a number of 0.5 or more and 1.5 or less. 7. A catalyst comprising the transition metal-supported complex according to claim 6 . 8. The catalyst according to claim 7 , wherein the catalyst is a catalyst for ammonia synthesis. 9. A method for producing ammonia, comprising contacting nitrogen and hydrogen with a catalyst, wherein the catalyst comprises an intermetallic compound represented by formula (1): RTX (1) wherein R represents a lanthanoid element, T represents a transition metal in period 4 or period 5 in the periodic table, and X represents Si, Al or Ge.
