METAL-LOADED ARTICLE CONTAINING TYPICAL ELEMENT OXIDE, CATALYST FOR AMMONIA SYNTHESIS AND METHOD FOR SYNTHESIZING AMMONIA

摘要

The present invention provides: a typical element oxide which is able to be easily synthesized, while enabling the achievement of a good balance between stabilization and improvement of the catalyst performance if used as a carrier for a catalyst; and a metal-loaded article which is obtained by loading the carrier with a transition metal. A metal-loaded article which is obtained by loading a carrier with a transition metal (M), and which is characterized in that the carrier is a composition that contains a typical element oxide represented by general formula (1). (1): AnBmOl(In general formula (1), A represents at least one element selected from the group consisting of Ba and Sr; B represents at least one element selected from the group consisting of Al, Ga, In, Si, Ge and Sn; n represents an integer from 1 to 17; m represents an integer from 1 to 17; and l represents an integer from 1 to 26.)
