Oxidative dimerization of methane over cerium mixed oxides and its relation with their ion-conducting characteristics
Abstract
Selectivities for ethene and ethane formation during oxidative dimerization of methane over cerium mixed oxide catalysts Ce1 –x Ybx02 – 0.5x and SrCe1 –x YbxO3 – 0.5 x appear to be related to the nature of their ionic conduction, decreasing with oxygen ion mobility while increasing with proton mobility.
