Response to Comments on "Efficient Photochemical Water Splitting by a Chemically Modified n-TiO ₂ "

Abstract

We do not disagree with the contention in the comment by Fujishima (1) that we should have cited the work of Fujishima et al. (2) in which titanium oxide was made by flame oxidation, a common method used both in our work (3) and that of other authors. However, the Fujishima et al. work has nothing else in common with ours. Our report (3) focused on citing works that reported high efficiency for water splitting; the Fujishima et al. study (2) is not among them. Although Fujishima (1) now maintains that we should have discussed the differences between his earlier work and our own, it would have been impossible in a two-page report to include all the differences separating our work with his and (logically) with that of all other authors who have reported in the literature on making titanium oxide by flame oxidation.
