Abstract: There is provided a cluster-supporting porous carrier having improved heat resistance and/or catalytic activity, and a method for producing it. The cluster-supporting porous carrier of the invention has porous carrier particles (20) such as zeolite particles, and metal oxide clusters (16) supported within the pores of the porous carrier particles. The method of the invention for producing the cluster-supporting porous carrier includes providing a dispersion containing a dispersing medium (11) and porous carrier particles dispersed in the dispersing medium, forming positively charged metal oxide clusters (16) in the dispersion, and supporting the metal oxide clusters within the pores of the porous carrier particles (20) by electrostatic interaction.
