Abstract
A method for producing highly dispersed catalysts is disclosed. The method includes contacting a support material with a solvent for a period of time, adding a metal salt to the solvent and support mixture, and then adding a reducing agent to the solution to reduce the metal salt to nanometer sized metal particles on the surface of the support. Excess solvent is used in the process, the volume of solvent being greater than two times the pore volume of the support.
