Abstract : The report is the fourth in a series dealing with propane electrooxidation on platinum at 100C in 12M H3PO4 using the technique of Electrochemical Mass Spectrometry (EMS). A study of oxidation processes is presented along with studies of propane adsorption at 0.40 V and 0.25 V, and at open circuit. The steady state current-potential curve for propane is discussed. The non-steady state oxidation of propane was studied at 0.40 V. Adsorption-desorption phenomena have been used to investigate the anodic behavior of propane at 0.40 V. The study was conducted principally to determine the effect of steady state oxidation on the adsorbate. The authors studied open-circuit adsorption of propane on platinum. The time dependencies of electrode phenomena at 0.25 V and at open circuit are presented and discussed. Using impurity corrected adsorption and charge data, the oxidation states of total, cathodically desorbable, and non-cathodically desorbable adsorbates formed at 0.25 V were determined. The results are summarized.
