In a recent paper (Seehra et al, Appl. Phys.Lett.90, 044104 (2007)), we have reported that with the use of an activated carbon in the anode compartment, pure H2 is produced in carbon-assisted water electrolysis at applied voltages E0 as low as 0.2V, compared to E0> 1.23V needed for unassisted water electrolysis. However, the kinetics of the reaction at the lower voltages is slower. In this work, we will report on the use of catalysts to improve the kinetics of this reaction at the energy-efficient lower voltages.
