Computational and Photoelectrochemical Study of Hydrogenated Bismuth Vanadate
Abstract
We demonstrate hydrogenation as a facile method to significantly enhance the performance of BiVO 4 films for photoelectrochemical water oxidation. Hydrogenation was performed for BiVO 4 films by annealing them in hydrogen atmosphere at elevated temperatures between 200 and 400 °C. Hydrogen gas can reduce BiVO 4 to form oxygen vacancies as well as hydrogen impurities. DFT calculation predicted that both oxygen vacancies and hydrogen impurities are shallow donors for BiVO 4 with low formation energies. These defects could increase the donor densities of BiVO 4 without introducing deep trap states. Electrochemical impedance measurements showed that the donor densities of BiVO 4 films were significantly enhanced upon hydrogenation. Hydrogen-treated BiVO 4 (H-BiVO 4 ) photoanodes achieved a maximum photocurrent density of 3.5 mA/cm 2 at 1.0 V vs Ag/AgCl, which is 1 order of magnitude higher than that of air-annealed BiVO 4 obtained at the same potential. The enhanced photoactivities were attributed to increased donor densities of H-BiVO 4, which facilitates the charge transport and collection.

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.
