Abstract

An improved cluster-supporting catalyst has heteroatom-removed zeolite particles, and catalyst metal clusters supported within the pores of the heteroatom-removed zeolite particles. A method for producing a cluster-supporting catalyst includes the following steps: providing a dispersion liquid containing a dispersion medium and the heteroatom-removed zeolite particles dispersed in the dispersion medium; and in the dispersion liquid, forming catalyst metal clusters having a positive charge, and supporting the catalyst metal clusters within the pores of the heteroatom-removed zeolite particles through an electrostatic interaction.
