The overreliance on the Schottky barrier model for reactions involving adsorbed intermediates must be revised to take into account the high surface state concentration to which they often give rise. This position is emphasized in that the most obvious environmental use of photoelectrochemistry is in splitting water to produce clean hydrogen.
