発明の名称 (英語) INTERMETALLIC COMPOUND, HYDROGEN STORAGE/RELEASE MATERIAL, CATALYST AND METHOD FOR PRODUCING AMMONIA NEW
発明の概要(英語) Provided are: an intermetallic compound which has high stability and activity; and a catalyst which uses this intermetallic compound. A hydrogen storage/release material which contains an intermetallic compound that is represented by general formula (1). RTX (1) (In the formula, R represents a lanthanoid element; T represents a transition metal of the fourth row or the fifth row of the periodic table; and X represents Si, Al or Ge.)
従来技術、競合技術の概要(英語) BACKGROUND ART
Typical ammonia synthesis method to the hard disk in the bar, the Bosch method, the number of Fe3O4 to Al2O3 mass % of K2O and containing iron as a catalyst to promote double (doubly promoted iron) is used, a mixed gas of nitrogen and hydrogen to the catalyst under high temperature and high pressure in contact with ammonia in a method of manufacturing.
On the other hand, the Haber, the Bosch method at a temperature lower than the reaction temperature of the ammonia synthesis method has been studied, as the catalytically active component (Ru) of ruthenium supported on a carrier for a variety of ammonia synthesis is used as a catalyst has been proposed (for example Patent Document 1). The catalyst is a transition metal such as Ru is used, its activity is very high, the Haber, the reaction conditions used in the Bosch method than, more benign conditions can be combined with ammonia is known. For example Haber, and a reaction temperature of 400°C is the Bosch method of 10mpa or more while the reaction pressure is required, using a Ru catalyst, a reaction temperature of about 200°C, and 1.1mpa or less, the reaction pressure is about atmospheric pressure and further the reaction can proceed is also known.
As a catalyst for the ammonia synthesis further, the intermetallic compound has been studied also. Having a high catalytic activity and a transition metal such as Ru and another metal element of the intermetallic compound is obtained, an inexpensive catalyst can be expected. Ammonia synthesis activity as an intermetallic compound, CaNi5, Mg2Ni, Mg2Cu such as an alkali metal or alkaline earth metal, an intermetallic compound of a transition metal (Patent Document 2) or, CeFe2, CeCo2, known as hydrogen storage alloys such as CeRu2 metal intermetallic compound (non-patent document 1, 2) and the like. Specifically, in non-patent document 1, instead of a simple substance of metal catalyst was prepared in the melt CeFe2, CeRu2, such as powder of an intermetallic compound CeCo2 ammonia synthesis was carried out using the result of the examination have been reported. Further, the intermetallic compound and the AB5 type intermetallic compound represented by the hydride reducing AB5H-6 is used as a catalyst has been proposed a method. Specifically the AB5 type as an intermetallic compound, and a misch metal as a main component A is La (mischmetal), an intermetallic compound of Ni and B is, BET specific surface area between the reducing compound and 0.02m2/g of a metal catalyst can be used as the hydride, in the ammonia synthesis at room temperature has been reported (Non-Patent Document 3).
Further, the intermetallic compound, a hydrogen embrittled in, broken, by escaping hydrogen can be obtained a fine intermetallic compound has been known.
