ChemInform Abstract
The catalytic activity for hydrogen conversion of Pt loaded on different carbon blacks by ion exchange with acidic functional groups on the carbon support depends on both the carbon support and the Pt solution used for loading. In the case of oxidized carbon black, exchange with a Pt(NH3)4Cl2 precursor solution leads to extremely small (0.75-1.7 nm) highly dispersed Pt parpticles on the carbon support and high activity in H2 oxidation. The catalytic activity strongly depends on the particle diameter of Pt rather than on the loading amount.
