Methane Activation on a La(0.6)Sr(0.4)Co(0.8)Fe(0.2)O(3) Perovsksite; Catalytic and Electrocatalytic Results

Abstract

The catalytic and electrocatalytic behaviour of the La(0.6)Sr(0.4)Co(0.8)Fe(0.2)O(3) (LSCF) perovskite deposited on yttria stabilized zirconia (YSZ), was studied during the reaction of methane oxidation. Experiments were carried out at atmospheric pressure, and at temperatures between 600 and 900 degrees C. When, instead of cofeeding with methane in the gas phase, oxygen was electrochemically supplied as O(2), considerable changes in the methane conversion and product selectivity were observed. The non-faradaic effects (NEMCA) were also studied and compared to those observed with metal catalysts.
