Abstract:

The dependency of n-TiO2 flatband potential V sub fb for cells of the general configuration n-TiO2Nafion 117, Redox speciesSnO2 conducting glass, was systematically studied for the redox species Rubpy32, Febpy32 and RuNH363 as a function of their concentration within the polymer. The linear relationship V sub fb M 1concentration b, was found to hold for all cells. The slope M was found dependent upon metal complex used and its oxidation state. The sensitivity of n-TiO2, V sub fb to its immediate chemical environment at its interface with the redox polymer can be a strategy pursued for chemical detection.
