Single electrode reaction comparison of experiment and theory

Single electrode reaction comparison of experiment and theory [Pg.468]

In this work, the main aim has been to determine the steady-state behaviour behaviour by measuring the current-potential curve. In general, the steady state is the most important characteristic of an electrode reaction. Fortunately, most known electrochemical reactions have a steady state and are variations of the redox type of reaction. As shown above, the steady current-potential curve can be exactly interpreted for redox reactions. In order carry out a complete analysis, it is essential to measure the components of the steady state by impedance-potential measurements. In addition, impedance delivers information about the charging processes as they appear in the high-frequency double layer capacity-potential curve. This last parameter is the parameter which should connect electrochemistry and surface science. The unfortunate fact is that it is still not very well understood. [Pg.468]

From the list of controlling parameters, a number of other possible ways [Pg.468]

The second method is to analyse the impedance-potential data on the basis of the equation [Pg.469]

Z(a ) - Ra Rct + (1 - jymo-w and produce an electrochemical spectrum as charge transfer-potential, double layer capacity-potential, ohmic resistance-potential, and Warburg coefficient-potential plots. Together with the current-potential curve, these present a useful representation of the steady-state electrochemical behaviour. [Pg.469]
