<P>PROBLEM TO BE SOLVED: To provide a hollow catalyst particle which enhances a utilization efficiency of catalyst particles. <P>SOLUTION: The utilization efficiency is enhanced by using the catalyst particle having a hollow structure. The catalyst particle having a hollow structure is prepared by mixing an organic solvent 10 containing a surfactant 20 with an aqueous solution containing a metal compound to form reversed micelle in which an aqueous solution 30 containing the metal compound is included by the surfactant 20 (Fig. b), supplying a compound capable of causing a reaction with water within the reversed micelle to solidify into the reversed micelle, forming a hollow particle having a solidified component 40 in the reversed micelle by causing a reaction with water within the reversed micelle on the outer face side and having a component 50 by which the metal compound is solidified on the inner face side (Fig. d) and removing the solidified component 40 by causing a reaction with water in the reversed water. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
