New Type of BiPO4 Oxy-Acid Salt Photocatalyst with High Photocatalytic Activity on Degradation of Dye
Abstract
A high photocatalytic BiPO(4) with a novel nonmetal oxy acid structure is synthesized by a hydrothermal method. BiPO(4) photocatalyst has an optical indirect band gap of 3.85 eV. In a comparison of BiPO(4) with that of TiO(2) (P25, Degussa), it is found that the photocatalytic activity of BiPO(4) is twice that of TiO(2) (P25, Degussa) for the degradation of methylene blue (MB) dye, while the BET surface of BiPO(4) is just one tenth of that of P25. Both the high position of the valence band and the high separation efficiency of electron-hole pairs result in the high photocatalytic activity. The inductive effect of PO(4)(3-) helps the e(-)/h(+) separation, which plays an important role in its excellent photocatalytic activity. It may extend to the synthesis of other inorganic nonmetal salts of oxy photocatalysts with suitable band gap and high activity for the environmental purification of organic pollutants in aqueous solution.

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.
