Abstract
The present invention is to provide a metal oxide sintered structure having a homogeneous catalyst supporting ability, and a production method therefor. Hardly reducing oxide powders and reducing oxide powders are mixed, and then kneaded with a binder. By extrusion molding, a structure comprising channels (fluid communicating holes) is formed. Then, after heating reaction and solid solution, it is reduced under an atmosphere containing a hydrogen. Thereby, a metal oxide sintered structure having the fluid communicating holes, with the metal particles precipitated on the surface is produced. The structure is suitable for use as a catalyst for a fuel cell, or the like.
