The Investigation of Propane Oxidation Using Electrochemical Mass Spectrometry.
Abstract
A theoretical analysis of the porous electrode used in previous propane oxidation studies was undertaken. The model transport through the porous platinum layer, porous Teflon membrane and the fritted glass support on the vacuum side of the interface is discussed. The model was tested experimentally using rotating porous electrodes, with and without a porous platinum layer. Experiments were performed at open circuit and at constant applied potential with and without a vacuum behind the glass frit of the electrode. The experimental results are consistent with the postulate of a solution diffusion layer existing adjacent to the porous metal, a porous metal layer filled with solution and a porous Teflon barrier containing pores largely unfilled with solution. In testing the model for the porous electrode using a rotating porous Teflon disk electrode, a new method for determining the diffusion coefficient of gases in water was devised and applied to argon and helium.
