• 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

• from solution during in two hours, suggesting a greater photocatalytic effectiveness than that of pure BiOI. To deposit metallic Bi on Bi2WO6 nanosheets, an in situ reduction approach using NaBH4 as the reducing agent was used [64]. Compared to pure Bi2WO6, Bi-coated Bi2WO6 absorbs more visible light

• , Huang et al. reported that BiOI microspheres served as self-sacrificing templates for in situ phase transformation and formation of phase junctions [81]. Different bismuth oxyiodides were formed as a result of this. Hierarchical BiOI, Bi4O5I2, Bi4O5I2–Bi5O7I phase-junction, and Bi5O7I may be synthesized

• pollutants such as tetracycline hydrochloride, bisphenol A (BPA), and RhB was used to measure the photocatalytic activity of the bismuth oxyiodides. The activity decreased in the sequence Bi4O5I2–Bi5O7I > Bi4O5I2 > BiOI, which is linked to charge separation efficiency and band structure. Engineered Bi

By tuning the ratio of
