Electrochemical promotion of ruthenium oxide catalysts for the gas phase combustion of ethylene

In this paper the electrochem. promotion of RuO2 catalyst was studied for the oxidn. of C2H4 to CO2 and H2O. The reaction rate can be increased of up to a factor of 115 by anodic polarization. A kinetic model for the simulation of the open circuit reaction rate is postulated. The model was found to be not applicable during polarization. The formation of a higher ruthenium oxide and/or the formation of backspillover species are supposed to affect the proposed model. [on SciFinder (R)]
