Abstract:
1. A method of synthesizing highly dispersed supported platinum catalyst comprising: (a) dissolving sodium alkoxide and platinum chloride in a solvent to produce a solution; (b) mixing the solution with a carbon support; (c) subjecting the solution mixed with the carbon support to ultrasonic treatment at about 30-60 Hz; (d) heating the solution mixed with the carbon support to temperatures ranging from about 5° C.-80° C.; (e) combining the solution mixed with the carbon support with a HCl solution; (f) optionally, filtering out the precipitates from the solution of step (a) to synthesize said catalyst; and (g) optionally, washing the catalyst with water, wherein the molar ratio of platinum chloride:sodium alkoxide ranges from about 1:4 to 1:8.
