Resumen:
The catalytic activity and selectivity of metals can be reversibly altered by supplying promoters electrochemically. This has been achieved by using a catalyst as the working electrode in a solid electrolyte electrochemical cell. In this letter we review the accepted explanation for the relationship between the catalyst work function (ewW) and the potential difference between the working and reference electrodes of the electrochemical cell (VWR). We show that thisexplanation is not correct. A theoretical derivation for the relationship found between ewW and VWR in some experiments is not presently available. For the moment, it must be considered only an experimental finding.
