Title:
ルテニウム担持触媒の製造方法
Document Type and Number:
Japanese Patent JP5677358
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for suppressing catalyst activity deterioration of reduced ruthenium.SOLUTION: In reduction of a catalyst composed of ruthenium supported on active carbon, oxidation activity of the reduced ruthenium is suppressed by carrying out reduction processing with an ammonia gas or an ammonia-containing gas in a reaction tube, and thereafter successively flowing the ammonia gas or the ammonia-containing gas through the reaction tube to adsorb ammonia on the reduced ruthenium.
