This value does not express the actual result since side and/or parallel reactions (e.g., H+ or 02 reduction) are not considered, but it does demonstrate the completeness of the cementation process and the effectiveness of this liquid-liquid extraction. During this extraction no external current flows through the phase boundary Hg (amalgam)/solution thereby establishing a potentiometric condition. The question of the potential difference at the phase boundary can be answered by constructing the experimentally accessible current-voltage curves for the reactions ... [Pg.230]

Here, the flat-band potential was neglected.) A typical set of drain current-voltage curves for various gate voltages is shown in Figure 14-8. [Pg.250]

In Fig. 16 we show a current-voltage curve for >-type GaP in the presence of a dye in the dark and at illumination with light being only absorbed by the dye. We see again a saturation current, now however, in cathodic direction. The photocurrent spectrum is represented in Fig. 17. It corresponds fully with the absorption spectrum of the adsorbed dye. One sees a saturation current at a polarisation of more than 0.35 eV negative of the flat band potential. Some special features at GaP-electrodes seem to be caused by the existence of surface states with energies in the range of the band gap. It has been assumed that these surface states can... [Pg.53]

In the absence of coupled homogeneous reactions, the current observed at an electrode is controlled by mass transport, electrode kinetics, or a mixture of the two. Control is wholly by mass transport at all points of a current—voltage curve for a reversible reaction and at the limiting current for quasi-reversible and irreversible reactions. [Pg.398]

Matsuda and co-workers have provided generic approximate expressions for current—voltage curves for first-order reactions at a variety of hydro-dynamic electrodes. They take the form... [Pg.403]

To use Faraday s law for the purpose at hand, the generator electrode reaction must be limited to the one of interest to assure that the charge consumed by the desired electron transfer reaction is essentially equal to the charge applied to the cell. Difficulties arise because it is not possible to control independently both the current and the electrode potential, and because only the current applied to the cell can be known directly in the experiment. A knowledge of the current-voltage curves for the precursor and the supporting electrolyte will provide valuable information for the design of practical experiments. [Pg.740]
