P-doped BiOCl for visible light photodegradation of tetracycline: An insight from experiment and calculation

Construction of Hexagonal Prism-like Defective BiOCL Hierarchitecture for Photocatalytic Degradation of Tetracycline Hydrochloride

“…Compared with pristine BiOCl, a distinct shift in diffraction peaks occurs in 3D BiOCl, in which the (001) and (012) peaks shift to a smaller diffraction angle, whereas the (110) peak shifts to a larger diffraction angle. The shift of (001), (012), and (110) peaks is about 0.06°, 0.03°, and 0.07°, respectively, in excess of the instrument bias of about 0.02°, suggesting an anisotropic distortion in the 3D-BiOCl crystal lattice, which is typically caused by lattice defects, such as substitutions and vacancies in the crystal [ 34 , 35 , 36 ].…”

“…Four characteristic vibration bands were detected in virgin BiOCl at 397.8, 199.4, 143.3, and 58.4 cm −1 , which are consistent with the majority of prior studies on BiOCl. Specifically, the peak at 397.8 cm −1 is corresponds to the B 1g and E g of the motorial oxygen atoms; the peak at 199.2 cm −1 is allocated to the A 1g internal stretching modes of Bi-Cl; and the peaks at 58.4 cm −1 and 143.3 cm −1 pertain to A 1g external and internal stretching modes of Bi-Cl, respectively [ 35 , 37 ]. When comparing 3D-BiOCl to BiOCl, three major differences in the spectrum were identified, including a blue-shift in the vibration peak, broadening of peaks, and the creation of a new peak at 95 cm −1 .…”

Rapid determination of SARS-CoV-2 nucleocapsid proteins based on 2D/2D MXene/P–BiOCl/Ru(bpy)32+ heterojunction composites to enhance electrochemiluminescence performance

“…The preparation of the 2D/2D MXene/P–BiOCl is performed via a solvothermal process according to a reported work with minor modifications [ 37 ]. Firstly, 5 mmol of Bi(NO 3 ) 3 ·5H 2 O is dissolved in 40 mL of ethylene glycol (C 2 H 6 O 2 ) with magnetically stirring to obtain transparent solution.…”

“…Regrettably, the fast charge recombination rate and weak visible light response limit the application of BiOCl. Heteroatom doping is an effective way to improve the property of BiOCl, among various elements, phosphorus (P) is beneficial to the electron-hole separation, interfacial charge transfer and visible light absorption, resulted by its remarkable electron donating capability, applicable radius and variable valence [ 37 ]. However, we also find that the ultrathin P-doped BiOCl (P–BiOCl) has some limitations in ECL application on account of its own poor water dispersion and low conductivity.…”

Construction of novel flower-like functionalized black phosphorus nanosheets/P-doped BiOCl S-scheme photocatalysts with improved photocatalytic activity in RhB and Cr(vi) degradation

“…The P-doped BiOCl shows a larger band gap with a more negative CB, facilitating the photodegradation of tetracycline. 9 BP nanosheets, a new two-dimensional semiconductor, have attracted much attention in various fields of application, including biomedicine, biosensing, supercapacitors, solar cells, etc. [10][11][12] They also exhibit great potential in photocatalysis due to their optical/electronic characteristics, such as outstanding light harvesting ability for a broad spectrum, a tunable band gap (0.3-2.0 eV) and high carrier mobility (B1000 cm 2 V À1 s À1 ).…”
