Summary: | A process for making a catalyst having precious metal nanoparticles deposited on a support includes first providing an aqueous dispersion of support particles. A pre-treatment slurry is prepared by mixing the aqueous dispersion of support particles with a water-soluble precious metal precursor and a reducing agent. The pre-treatment slurry is hydrothermally treated at a temperature in the range of from about 40° C. to about 220° C. for a time sufficient to deposit precious metal nanoparticles on the surface of the support particles, the precious metal nanoparticles having an average particle size less about 50 nm. |
