Temperature programmed desorption/reduction techniques have been applied to an investigation of the interaction of hydrogen with oxygen surface complexes and reactive sites on the surface of a resin char during thermal desorption. It is shown that the presence of hydrogen has a number of significant effects on the evolution patterns of the oxides of carbon and water vapor. A number of conclusions...
The influence of support surface chemistry and metal precursor species on the properties of Pt/C catalysts has been analyzed. The char of a phenolformaldehyde polymer is the carbon source for obtaining four different supports: three with different degree of surface oxidation and another one modified by ion-exchanged calcium. These supports have been impregnated with aqueous solutions of two platinum...
