<P>PROBLEM TO BE SOLVED: To provide a catalyst produced at low cost and formed by having a desired metal supported on the surface of a ferroelectric body, and a method for producing the same. <P>SOLUTION: The catalyst is formed by having the metal supported on the surface of the powdered ferroelectric body, wherein the metal is supported in such a manner that a distance from the surface of the ferroelectric body to the surface of the metal is 10 nm or less. The catalyst is produced by having the metal supported on the surface of the ferroelectric body through a mixing process of mixing the powdered ferroelectric body and powdered metal to produce a mixture, and a firing process of firing the obtained mixture while stirring it. After the firing process, metal which is not supported on the ferroelectric body is removed by dissolving it in an acid solution or an alkaline solution in a washing process. In the washing process, a part of the metal which is supported on the ferroelectric body is etched. <P>COPYRIGHT: (C)2012,JPO&INPIT |
