“…Unlike BiOCl materials, bismuth oxybromides have the ability to carry out oxidation-reduction reactions driven by visible light irradiation, because of their slightly narrower band-gap energy (∼2.7 eV). However, their fast charge recombination rate and low redox capacity have driven the construction of new BiOBr-based structures ( Guo et al, 2021 ). In this context, Paquin et al (2015) synthesized BiOBr nanostructures decorated with vertically aligned ZnO nanorods (ZnO/BiOBr).…”

An important target of photoelectrocatalysis (PEC) technology is the development of semiconductor-based photoelectrodes capable of absorbing solar energy (visible light) and promoting oxidation and reduction reactions. Bismuth oxyhalide-based materials BiOX (X = Cl, Br, and I) meet these requirements. Their crystalline structure, optical and electronic properties, and photocatalytic activity under visible light mean that these materials can be coupled to other semiconductors to develop novel heterostructures for photoelectrochemical degradation systems. This review provides a general overview of controlled BiOX powder synthesis methods, and discusses the optical and structural features of BiOX-based materials, focusing on heterojunction photoanodes. In addition, it summarizes the most recent applications in this field, particularly photoelectrochemical performance, experimental conditions and degradation efficiencies reported for some organic pollutants (e.g., pharmaceuticals, organic dyes, phenolic derivatives, etc.). Finally, as this review seeks to serve as a guide for the characteristics and various properties of these interesting semiconductors, it discusses future PEC-related challenges to explore.

“…BiVO 4 is a kind of visible light photocatalyst that has the advantages of low bandgap energy, green environmental protection, low cost, high stability, and antibacterial activity [ 3 , 4 ]. However, there are some shortcomings of BiVO 4 , such as narrow band gap, poor adsorption capacity, and fast electron hole recombination rate [ 5 ]. In order to overcome the above issues, researchers have focused on the modification of BiVO 4 with other materials [ 6 , 7 , 8 , 9 , 10 , 11 , 12 ].…”

In this study, a photocatalytic antibacterial composite of polydopamine-reduced graphene oxide (PDA-rGO)/BiVO4 is prepared by a hydrothermal self-polymerization reduction method. Its morphology and physicochemical properties are characterized by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), Fourier-transform infrared (FT-IR), and X-ray diffraction (XRD). The results indicate that BiVO4 particles are evenly distributed on the rGO surface. Escherichia coli (E. coli) MG1655 is selected as the model bacteria, and its antibacterial performance is tested by flat colony counting and the MTT method under light irradiation. PDA-rGO/BiVO4 inhibits the growth of E. coli under both light and dark conditions, and light significantly enhances the bacteriostasis of PDA-rGO/BiVO4. A combination of BiVO4 with PDA-rGO is confirmed by the above characterization methods as improving the photothermal performance under visible light irradiation. The composite possesses enhanced photocatalytic antibacterial activity. Additionally, the photocatalytic antibacterial mechanism is investigated via the morphology changes in the SEM images of MG1655 bacteria, 2′,7′-dichlorofluorescein diacetate (DCFH-DA), the fluorescence detection of the reactive oxygen species (ROS), and gene expression. These results show that PDA-rGO/BiVO4 can produce more ROS and lead to bacterial death. Subsequently, the q-PCR results show that the transmembrane transport of bacteria is blocked and the respiratory chain is inhibited. This study may provide an important strategy for expanding the application of BiVO4 in biomedicine and studying the photocatalytic antibacterial mechanism.

“…BiOX (X=F, Cl, Br, I) is one kind of the most potential visible-light-drived photocatalyst [8][9][10][11]. It possesses an anisotropic layered structure, in which the X − ions can easily insert into the [Bi 2 O 2 ] 2+ layers and thereby constructing an internal electric field along the [001] direction [12,13]. Moreover, BiOX is one of the indirect band gap semiconductors, which means that the photoinduced electrons must pass through a certain k-space distance before they reach the conduction band [12,14].…”

A novel BiOCl microsphere with high (110) facets exposure is successfully synthesized via a one-step solvothermal process in the presence of ethylene glycol without any other surfactant. The percentage of exposed (110) facets can be easily controlled by reactant concentration. The obtained BiOCl microsphere exhibited excellent photocatalytic efficiency for degradation of Rhodamine B (RhB). Under visible light irradiation, 100 ml 20 mg/L RhB can be completely decomposed in only 45 min. The excellent performance can be attributed to the efficient separation of photogenerated electrons and holes benefited from the special electronic structure of BiOCl microspheres. The (110) crystal facets are beneficial for holes transfer while the electrons migrate in [001] direction which is perpendicular to the (110) facet, thus extending the lifetime of photoinduced charges. This study may open more possibilities for the rational design and controllable synthesis of visible light photocatalysts with excellent performance.
