Electrochemcial Promotion of RuO2 Catalyst Dispersed on an Yttria-Stabilized Zirconia Monolith

摘要

Electrochemical promotion of dispersed RuO2catalyst on yttria-stabilized zirconia (YSZ) monolith was studiedin a monolithic catalytic reactor fabricated from YSZ solidelectrolyte. This new design has shown an important increase inethylene conversion to CO2 by potential application between twoinert gold electrodes. The effects of the cell potential, theethylene partial pressure, the total gas flux, and the temperaturewere studied. In a typical example, an increase of the ethyleneconversion from 36 to 50.5% (pC2H4=0.2 kPa) was observed byapplying a cell potential of 30 V at 360℃.
