The purpose of the present work is to elucidate on carbon black materials as a support for high loading of Pt in highly dispersed form. There are three main methodologies described in the .literature for deposition of Pt: i) impregnation of the support with solution of well soluble Pt precursors, ii) deposition of a colloidal form of Pt onto the support, and iii) deposition of Pt onto the supports from microemulsion of Pt precursor with the assistance of surfactant. The Pt containing species are deposited either by spontaneous adsorption or by evaporation of the solvent. The deposited platinum compound is transformed to metallic platinum with some chemical or physical (temperature) treatment. Remainders of the deposited compound other than platinum must be removed from the catalysts (for instance by washing, calcination, etc.).
