Abstract
This disclosure deals with novel supported platinum catalysts and methods of producing the same by the uniform deposition of colloidal meta-stable, and thus transient, platinum metal particles on the surface of substrates of widely-varying specific surface areas, such particles resulting preferably from the complex sulfite and the like oxidized by a solution of hydrogen peroxide or like oxidant.
