N2 - By combining two experimental techniques, electrochemical impedance spectroscopy (EIS) and the coplanar electrodes-gap configuration, we monitored the electronic conductivity in nanoporous TiO2 in aqueous solution (pH 2) as a function of the electrode potential. As a result of electron accumulation the conductivity varies over more than eight orders of magnitude up to a maximum σ = 3.7 × 10-3 Ω-1 cm-1.
