ABSTRACT:
Disclosed is a particle-bearing composite comprising a solid carrier and polymer-protected particles adsorbed thereon, wherein the polymer has a number average molecular weight of 3,000 to 300,000 and the particles are of a metal and/or a metal compound. The particle-bearing composite of the present invention is produced by a method in which a polymer-protected colloidal dispersion, which is comprised of a dispersion medium, colloidal metallic particles and/or metal compound particles dispersed in the dispersion medium and a protective polymer having a number average molecular weight of 3,000 to 300,000 and serving as a protective colloid for protecting the colloidal particles, is contacted with a solid carrier. The particle-bearing composite of the present invention can exhibit excellent catalytic performances with high reproducibility when used as an active component-bearing type catalyst, and can also be advantageously used in the fields of electric and magnetic materials because the metallic particles and/or metal compound particles uniformly borne by the solid carrier in the particle-bearing composite of the present invention can exert excellent electric and magnetic performances.
