Method for producing heterogeneous catalysts containing metal nanoparticles

摘要

A monomer is added to a solvent containing metal salt and porous support materials and the solvent is stirred for a period of time to distribute and fix the metal in the pores of the support materials. The solids that are dispersed in the solvent are then separated from the liquid, dried and calcined to form heterogeneous catalysts. The monomer that is added is of a type that can be polymerized in the solvent to form oligomers or polymers, or both. When forming heterogeneous catalysts containing platinum, acrylic acid is selected as the preferred monomer.

1. A method for producing a supported catalyst, comprising:
mixing a metal oxide support material with a metal salt in a solvent; adding a monomer to the solvent containing metal salt and the metal oxide support materials, the monomer being of a type that can be polymerized in the solvent to form oligomers or polymers, or both; reducing the metal salt using the monomer by stirring the solvent containing the metal salt, the support materials and the monomer; separating the liquid from the solid in the solvent; and calcining the separated solid to produce the supported catalyst.
