Emerging strategies in the sustainable removal of antibiotics using semiconductor-based photocatalysts
Beilstein J. Nanotechnol. 2025, 16, 264–285, doi:10.3762/bjnano.16.21
- , attributed to the increased specific surface area and absorption capacity. Using a one-step hydrothermal process, Wu et al. [69] synthesized Bi-bridged Z-scheme BiOCl/Bi2O3 heterojunctions. The constructed binary photocatalysts exhibited 94.79% TC degradation efficiency owing to the enhanced separation of
- bandgaps of the different compounds are as follows: 3.22 eV (BiOF), 2.80 eV (BiOCl), 2.36 eV (BiOBr), and 1.75 eV (BiOI) [85]. Although BiOCl has a larger bandgap, it is considered a more promising photocatalyst than BiOI and BiOBr [90]. For example, BiOCl microspheres were able to remove 91.90% of TC
- recombination of electrons and holes and facilitated the direct attack of h+ on the surface of BiOCl [84][91]. This was verified by monitoring the lower effectiveness of BiOI [92] and BiOBr [93] in removing antibiotics. The photocatalytic activity of BiOX varies based on the dipole moment; the efficiency is
Recent trends in Bi-based nanomaterials: challenges, fabrication, enhancement techniques, and environmental applications
Beilstein J. Nanotechnol. 2022, 13, 1316–1336, doi:10.3762/bjnano.13.109
- , BiOCl, and (BiO)2CO3, most Bi-based compounds have bandgaps that may be stimulated by visible light. As a result, much interest in environmental cleanup and energy conversion research has been sparked by Bi compounds [24]. Because of their advanced photocatalytic process, more and more publications on
- energies. Many persistent organic contaminants can be degraded at room temperature through the oxidizing power of VB holes in bismuth oxyhalides [26]. BiOCl, BOI, BiOBr, and composites made from them have been widely reported due to their excellent photocatalytic properties [27][28][29]. However, the
- simple hydrothermal synthesis for preparing 2D BiOCl nanosheets [83]. This was accomplished by altering the pH value of the precursor solution and using of dulcitol (C6H14O6) as surfactant. The pH value substantially influenced the thickness of the nanosheets and the fraction of exposed (001) facets. The
Rapid fabrication of MgO@g-C3N4 heterojunctions for photocatalytic nitric oxide removal
Beilstein J. Nanotechnol. 2022, 13, 1141–1154, doi:10.3762/bjnano.13.96
- redox potential by coupling two or more semiconductors [23][24], such as Bi2MoO6-based [25][26][27][28][29], BiOCl-based [30][31], g-C3N4-based [32][33][34], ZnO-based [35][36][37], TiO2-based [38][39], and MgO-based heterostructured photocatalysts [40]. Among these, the combination of MgO and g-C3N4
Spindle-like MIL101(Fe) decorated with Bi2O3 nanoparticles for enhanced degradation of chlortetracycline under visible-light irradiation
Beilstein J. Nanotechnol. 2022, 13, 1038–1050, doi:10.3762/bjnano.13.91
- construct Bi2O3-based heterojunctions has attracted extensive interest. A large number of Bi2O3-based heterojunctions, such as Bi2O3/g-C3N4 [46], WO3/g-C3N4/Bi2O3 [47], Bi2O3/BiOCl [48], Bi2O3/ZnO [49], and Bi2O3/BiVO4 [50] have been synthesized. However, to the best of our knowledge, there is no report
BiOCl/TiO2/diatomite composites with enhanced visible-light photocatalytic activity for the degradation of rhodamine B
Beilstein J. Nanotechnol. 2019, 10, 1412–1422, doi:10.3762/bjnano.10.139
- Abstract A BiOCl/TiO2/diatomite (BTD) composite was synthesized via a modified sol–gel method and precipitation/calcination method for application as a photocatalyst and shows promise for degradation of organic pollutants in wastewater upon visible-light irradiation. In the composite, diatomite was used as
- a carrier to support a layer of titanium dioxide (TiO2) nanoparticles and bismuth oxychloride (BiOCl) nanosheets. The results show that TiO2 nanoparticles and BiOCl nanosheets uniformly cover the surface of diatomite and bring TiO2 and BiOCl into close proximity. Rhodamine B was used as the target
- degradation product and visible light (λ > 400 nm) was used as the light source for the evaluation of the photocatalytic properties of the prepared BTD composite. The results show that the catalytic performance of the BTD composite under visible-light irradiation is much higher than that of TiO2 or BiOCl
Electronic properties of several two dimensional halides from ab initio calculations

- with density functional theory (DFT) [27] were conducted to study the physical and chemical properties of bulk BiOX compounds as a complement to experiments [28]. In 2006, Zhang et al. [17] calculated the electronic structure of bulk BiOCl with the tight-binding linear muffin-tin orbital (TB-LMTO) code
- the one of AcOBr and the structures of GaOF and InOF are analogous to the one of CrOF. Accordingly, the corresponding geometries are not shown in Figure 1. In the same way, in Figure 2, we show the crystal structures of the chloride and iodide monolayers (AcOCl, BiOCl, YOI, and ScOI). The geometries
- to the fact that the PBE functional is usually overestimating equilibrium lattice parameters (although the opposite is seen for BiOCl), to the fact that experiments are not done at T = 0, or to the fact that we are comparing data of bulk structures while our calculation are performed on monolayers
