Abstract:
1. A method of making palladium-containing nanoscale catalyst particles comprising placing a starting material in a reaction chamber, subjecting the starting material to a beam of laser energy to form a vapor and condensing the vapor so as to form first nanoscale particles and second nanoscale particles, wherein the first nanoscale particles comprise palladium or an oxide of palladium, the second nanoscale particles are selected from the group consisting of aluminum, silicon, zirconium and cerium, and the first nanoscale particles are supported on the second nanoscale particles to form the palladium-containing nanoscale catalyst particles, wherein the reaction chamber has an upper portion and a lower portion and wherein the temperature maintained in the upper portion is less than the temperature maintained in the lower portion such that the condensing occurs in the upper portion.
