Abstract
The potential‐dependent optical‐absorption spectroscopy of nanostructured (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 sites. © 2000 The Electrochemical Society.
