Electrochemical Promotion Using a Bipolar Monolithic Reactor

3 Electrochemical Promotion Using a Bipolar Monolithic Reactor 

A brilliant demonstration of the bipolar design concept came recently from the group of Comninellis atEPFL (Fig. 12.10).9 

A monolith was made from YSZ and the surface of the monolith channels was covered with a Ru02 catalyst. Two terminal Au electrodes were deposited on the outside surface of the monolith. Potential application between the two terminal Au electrodes was found to induce NEMCA on the Ru02 catalyst which is not in electrical contact with any metal wire.9 

The faradaic efficiency A values for C2H4 oxidation are on the order of 103 while C2H4 conversion could be enhanced from 35% to 50% (Fig. 12. II).9
