Abstract:

The electrochemical reactions of CH4, C3H8, n-C6H14, and CO2 on platinum electrodes in 80 H3PO4 at 130C were investigated. Experimental studies of steady state kinetics, steady state adsorbate coverage on smooth and platinized Pt, and the kinetics of oxidation of the adsorbed layers have been made. Steady state coverage with C3H8, n-C6H14, and reduced CO2 is lower on platinized Pt than it is on smooth Pt. C3H8 coverage is much more pressure sensitive on platinized Pt. When CH4 is adsorbed on smooth Pt, it appears to break down rapidly to form O-type. This indicates the high reactivity of C1 radicals compared with O-type. Little or no CH-alpha is formed. At low potentials or 0.30 v vs. RHE the rate of C3H8 oxidation decreases with increase in pressure. Studies of the reactions of the O-type adsorbate with C3H8 on platinized Pt allow the tentative assignment of 8-10 electrons for each 3 carbon atoms for the step O-type to CO2.
