Abstract: The aim of this work was to elucidate on the methods of Pt deposition on carbon black to achieve high loadings of Pt of about 60 wt.% in highly dispersed form. The carbon black supports were characterized by nitrogen physisorption. Platinum was deposited on the supports: from true solutions of H2PtCl6, Pt(C5H7O2)2, Pt(NH3)4(NO3)2, or Pt(NH3)2(NO2)2, and from fine dispersions of Pt(C5H7O2)2, PtO2, Pt(NH3)4(OH)2. Atomic adsorption spectroscopy, AAS, and scanning electron microscopy, SEM, were used for elemental analysis and determination of Pt content. The deposited Pt species were dried, calcined or reduced and were subjected to temperature programmed reduction, TPR. After degassing at increased temperature, the Pt dispersion was determined by hydrogen chemisorption at -60 C.
