Crystal facet-dependent photocatalytic oxidation and reduction reactivity of monoclinic WO3 for solar energy conversion
Abstract
The reactivity of a photocatalyst is basically influenced by its surface atomic and linked electronic structure. Tuning different crystal facets is becoming an important strategy to optimize the reactivity of a photocatalyst for targeted reactions. Here we report a facile and new route of synthesizing a quasi-cubic-like WO3 crystal with a nearly equal percentage of {002}, {200} and {020} facets, and a rectangular sheet-like WO3 crystal with predominant {002} facet by controlling acidic hydrolysis of crystalline WB. As a result of electronic structure effects induced by crystal facet, the quasi-cubic-like WO3 crystal with a deeper valence band maximum shows a much higher O2 evolution rate in photocatalytic water oxidation than the rectangular sheet-like WO3 crystal. The latter, with an elevated conduction band minimum of 0.3 eV, is able to photoreduce CO2 to generate CH4 in the presence of H2O vapor.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
