(57) [Summary] [Purpose] In addition to being able to set the particle size of the catalyst material regardless of the amount of catalyst material supported, it is homogeneous and does not change the catalyst particle size during catalyst production, and has a long life and high activity. To provide a catalyst having a metal oxide as a carrier. [Structure] The method comprises hydrolyzing a metal alkoxide as a carrier raw material in the presence of water with stirring in a dispersion liquid of ultrafine particles having catalytic activity to generate colloidal metal oxide particles. And a method for producing a supported catalyst. The dispersion of ultrafine particles was made by using a microemulsion having an aqueous solution containing a water-soluble metal compound as droplets of ultrafine particles as a raw material and insolubilizing the water-soluble metal compound contained in the droplets. What is claimed is: 1. A method for producing the supported catalyst, wherein The method for producing a supported catalyst, wherein the insolubilization of the water-soluble metal compound is a reduction reaction. |
