発明の名称 (英語) Ru Cu SOLID SOLUTION NANOPARTICLES, PRODUCTION METHOD THEREFOR, AND CATALYST
発明の概要(英語) The present invention provides Ru Cu solid solution nanoparticles wherein Ru and Cu form a solid solution at the atomic level.
従来技術、競合技術の概要(英語) BACKGROUND ART
Platinum group elements for automobile exhaust gas processing, such as hydrogenation as the function of the catalyst, or plating or the like is used, a small amount of expensive production. For this reason, the use amount of the platinum group element is demanded a technique which can reduce. In addition, since the strict environmental regulations, a technique which can reduce the amount of toxic elements is demanded. Electronic structure by fusion between elements optimized ' artificial elements' to be manufactured and these problems can be solved, for the practical use is absolutely imperative for the established synthetic techniques. Is a platinum group element in the organic synthesis reaction catalyst including Ru as, a fuel cell for home ene-farm catalyst poisoning of carbon monoxide, ammonia synthesis catalyst, such as NOx in the exhaust purifying catalyst, platinum-free electrode of a fuel cell catalyst or the like, a wide variety of used rare and is very useful as a catalyst. Recently computer or to increase the capacity of hard disk DVD for used also as a memory material.
(Cu) ruthenium (Ru) is copper, an alloy state in the figure also does not dissolve in a liquid state (not mix at the atomic level) alloy system.
Is Patent Document 1-3, and Ru and alloys of cu but, also in a liquid state and cu Ru is not a solid solution, the alloy is not a solid solution.
