Abstract
Addition of methyl viologen (MV**2** plus ) enhances the currents observed for TiO//2 suspensions under ilumination by trapping of photogenerated electrons with formation of MV** plus . The magnitude of the photocurrent depends upon the relative location of the semiconductor Fermi level and E//r//e//d//o//x of the MV**2** plus /MV** plus multiplied by (times) couple. The location of the Fermi level and the analysis powders was estimated as minus 0. 05 V vs. NHE (pH 0) based on the observed variation of photocurrent with pH. The shift in the quasi-Fermi level with light intensity is also discussed.
