摘要：

The catalytic and electrocatalytic oxidation of methane to ethane and ethylene was studied at 900-degrees-C over a gold-supported yttria-stabilized zirconia (Au-YSZ) catalyst. The catalyst was found to be active for C2 formation with C2 selectivities up to 67% and C2 yields up to 15%. Yttria-stabilized zirconia compared favorably to unstabilized yttria-zirconia. Electrochemical oxygen pumping was investigated and found to affect product distribution.
