Electron accumulation in nanostructured TiO{sub 2}(Anatase) electrodes

· Journal of the Electrochemical Society
The potential-dependent optical-absorption spectroscopy of nanostructured TiO{sub 2} (anatase) is most fully accounted for by two processes, band-filling and intercalation. Under weak-accumulation conditions, occupation of surface and conduction-band states by electrons dominates with the accumulated charge being compensated by adsorbed protons or cations. Under strong-accumulation conditions, however, intercalation of protons or cations may take place with a fraction of the accumulated electrons being localized at Ti{sup IV} sites.
