Synthesis and Enhanced Visible-Light Photoelectrocatalytic Activity of p−n Junction BiOI/TiO2Nanotube Arrays
Abstract
p − n junction BiOI/TiO 2 nanotube arrays (NTs) were prepared by coating BiOI on the tube wall of the self-organized TiO 2 NTs using a novel impregnating−hydroxylation method. The as-prepared samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and UV−vis absorption spectroscopy. The photoelectrocatalytic (PEC) activity toward degradation of methyl orange (MO) aqueous solutions under visible-light irradiation (λ > 420 nm) by p − n junction BiOI/TiO 2 NTs was investigated. The results from the current study demonstrate that the as-prepared BiOI/TiO 2 junction NTs display much greater PEC activity than the respective pure BiOI and TiO 2 counterparts due to the synergetic effects of several factors including the strong visible absorption, the formation of p − n junction, and the impact of external electrostatic field. The proposed mechanism responsible for the enhanced performance was further confirmed by the transient photocurrent response experiments.

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.
