The advanced structural design of semiconductor photoactive materials is the core element to improve the performance of photoelectrochemical (PEC) biosensors. By constructing a BiOIO 3 @Bi 4 O 5 Br 2 Z-Scheme heterojunction with abundant oxygen vacancies to significantly improve the photoelectric conversion efficiency, a sensitively PEC biosensor for MBD2 detection was designed by combining DNA isothermal cycle double amplification technology. Specifically, the chitosan-modified BiOIO 3 @Bi 4 O 5 Br 2 was modified on the surface of ITO electrode. Methylene blue (MB)-DNA was immobilized on due to the covalent reaction of its carboxyl group with the amino group of chitosan, and the excess amino group was blocked with acetaldehyde. In the absence of MBD2, the cleavage activity of HpaII is inhibited due to the retention of cytosine methylation. which triggers ISDPR and large amounts of single-stranded DNA complementary to MB-DNA was produced. After MB-DNA hybridization, Exo III was triggered to assist the MB-DNA hydrolysis cycle, resulting in the drop of MB, causing a decrease in the photoelectric signal. Conversely, in the presence of MBD2, it removed cytosine methylation, triggering HpaII hydrolysis and inhibiting subsequent reactions, so that the MB connected to the electrode is retained and the photoelectric signal is enhanced. The sensor had a detection range from 0.07 to 500 ng/mL with a detection limit of 0.018 ng/mL (3σ). The study also explores the effects of environmental pollutants on MBD2 activity and validated with molecular docking models, offering insights into epigenetic regulation and environmental health assessments. This work underscores the potential of advanced photoactive materials and heterojunction designs in biosensor applications.

Co-catalysts can achieve efficient separation of photogenerated carriers and are considered as a promising strategy for solar photocatalytic removal of pollutants. Herein, we reported the synthesis of nanocomposite of BiOIO 3 /Ti 3 C 2 MXene combining two dimensional 2D BiOIO 3 with 2D Ti 3 C 2 MXene co-catalyst. The few-layered 2D Ti 3 C 2 MXene provided more adsorption and reaction sites. Furthermore, the synergism of intimate interfacial contact between the two 2D nanosheets and robust metallic electrical conductivity of Ti 3 C 2 MXene significantly accelerated the separation and migration of photogenerated charge carriers. A variety of organic pollutants were proved to be effectively degraded by 2D/2D BiOIO 3 /Ti 3 C 2 MXene composites. The degradation efficiencies followed the order tetracycline hydrochloride (93.4 %) > diclofenac sodium (87.6 %) > levofloxacin hydrochloride (77.4 %) > 4-nitrophenol (43.3%). Besides, the satisfactory recycling and stability of BiOIO 3 /Ti 3 C 2 MXene for the degradation of organic pollutants in water under solar irradiation predicted its good prospect for practical applications.

Increasing insertion host materials are developed as high-performance anodes of “rocking-chair” zinc ion batteries. However, most of them show unsatisfactory rate capabilities. Herein, layered BiOIO3 is reported as an excellent insertion host and a zinc ion conductor, i.e., Zn3(PO4)2·4H2O (ZPO), is introduced to construct a BiOIO3@ZPO heterojunction with a built-in electric field (BEF). Both ZPO and a BEF obviously enhance Zn2+ transfer and storage, which is proven by theoretical calculations and experimental studies. The conversion-type mechanism of BiOIO3 is revealed through ex situ characterizations. The optimized electrode exhibits a high reversible capacity of 130 mAh g–1 at 0.1 A g–1, a low average discharge voltage of 0.58 V, an ultrahigh rate performance with 68 mAh g–1 at 5 A g–1 (52% of capacity at 0.1 A g–1), and an ultralong cyclic life of 6000 cycles at 5 A g–1. Significantly, the BiOIO3@ZPO//Mn3O4 full cell shows a good cyclic life of 67 mAh g–1 over 1000 cycles at 0.1 A g–1. This work provides a new insight into the design of anodes with excellent rate capability.

The ternary complex photocatalysts of BiOIO 3 /g-C 3 N 4 /MoS 2 by solvent-exfoliation method was synthesized for the first time. In the typical procedure, the BiOIO 3 /g-C 3 N 4 was obtained via hydrothermal synthesis technique, and then the BiOIO 3 /g-C 3 N 4 /MoS 2 photocatalysts were prepared via ultrasonic solvent-exfoliation method from bulk commercial MoS 2 in the alcohol solution. The samples of BiOIO 3 /g-C 3 N 4 /MoS 2 were analyzed by PL , XRD and other characterization analysis methods. The photocatalytic activity of the as-prepared samples was investigated by removing gas phase mercury irradiation under visible light . The as-prepared BCM-0.3 exhibits excellent photocatalytic performance, being with the highest efficiency of 70.58%. Owing to the electronic channels of field-effect, an internal electric field was formed through the corresponding band-gap engineering, improving photocatalytic reaction. Besides, the excellent activity of the ternary photocatalysts BiOIO 3 /g-C 3 N 4 /MoS 2 is attributed to heterostructure between BiOIO 3 /g-C 3 N 4 and MoS 2 , which enlarges spectral response and improved separation efficiency of charge carriers, and MoS 2 -composing, which provides more active sites for catalytic oxidation . In addition, the as-prepared samples with excellent photocatalytic performance also offer a perspective insight into the hydrogen evolution , CO 2 conversion and degradation of organic pollutants.

Broadening the light absorption and inhibiting carrier's recombination are vital to the improvement of photocatalytic performance. Herein, self-assembly 3D hierarchical microsphere BiOIO 3 /Bi 5 O 7 I Z-scheme heterojunction with carrier transfer channel was firstly fabricated by in-situ solvothermal method. The degradation efficiency for bisphenol A (BPA) reached 98.9 % within 60 min visible light irradiation. The enhanced photocatalytic activity was benefited from the Z-scheme system assisted by iodate/iodide (IO 3 - /I - ) as carrier transfer channel that not only accelerated the interfacial charge separation, but also provided massive reactive centers for obtaining high redox capacity. The vulnerable sites and the degradation pathways of BPA were identified by density functional theory calculations and liquid chromatography-mass spectrometry analyses. The toxicity of BPA and its intermediates were predicted by ECOlogical Structure Activity Relationship (ECOSAR) and the results demonstrated that BPA was eventually mineralized to harmless products. The Z-scheme charge transfer mechanism was deeply elucidated based on the role of active species (·O 2 - , ·OH and h + ), band structure and carrier separation efficiency. This study provides a promising strategy for the photoactivity enhancement of bismuth based heterojunction in environment purification.

5CuO/BIO shows rate constants 11.04 and 5.69 times those of CuO and BIO. • The heterojunction accelerates the Cu 2+ /Cu + cycle to efficiently activating persulfate. • LSV demonstrates the electron transfer between the catalyst and PS. • Possible degradation pathways of OTC were inferred using LC-MS and DFT calculations. Persulfate-based advanced oxidation processes (AOPs) are promising for antibiotic degradation, yet efficient and sustainable persulfate (PS) activation remains challenging. Herein, a novel S-scheme heterostructure CuO/BiOIO 3 (CuO/BIO) was synthesized via an in-situ calcination method. Under illumination, the CuO/BIO heterojunction synergistically activated PS, substantially enhancing the photocatalytic degradation of oxytetracycline (OTC). The optimal 5CuO/BIO/PS system achieved an excellent degradation rate constant (k) of 0.0740 min −1 , which is 11.04 and 5.69 times higher than those of CuO/PS and BIO/PS, respectively. X-ray photoelectron spectroscopy (XPS) revealed that the synergistic interaction between CuO and BIO promotes the Cu 2+ /Cu + redox cycle. Photoluminescence (PL) and electrochemical impedance spectroscopy (EIS) demonstrated the superior charge separation capability of the CuO/BIO composite. Linear sweep voltammetry (LSV) confirmed a synergistic effect between photocatalysis and PS activation, which facilitates electron transfer from the catalyst to PS. Additionally, the OTC degradation pathway was elucidated by liquid chromatography-mass spectrometry (LC-MS) identification of intermediates combined with theoretical calculations. Collectively, this study addresses a research gap in the CuO/BIO photocatalytic synergistic PS system and provides both a theoretical basis and experimental evidence for its application in treating antibiotic-containing wastewater.

Imidazolinone herbicides such as imazethapyr (IMT) pose potential ecological risks due to their high mobility and ecotoxicity. This study synthesized the bismuth-based photocatalyst BiOIO3via a facile hydrothermal method and systematically characterized its physicochemical properties. BiOIO3features a 2D lamellar structure, pure phase composition, and a built-in internal polarization electric field that efficiently separates photogenerated electron–hole pairs. Photocatalytic experiments exhibited that BiOIO3achieved 84.5% elimination of IMT, with a rate constant 66 times higher than that of TiO2(Rutile). Mechanistic studies revealed that photogenerated electrons (e−), holes (h+), and superoxide radicals (·O2−) are the primary reactive species. HPLC-MS/MS identified key intermediates, and QSAR-based toxicity prediction showed reduced mutagenicity for most intermediates. Importantly, BiOIO3effectively eliminated five imidazolinone herbicides simultaneously. This work highlights BiOIO3as a promising photocatalyst for efficient and practical remediation of imidazolinone herbicide-contaminated water.

BiOIO 3 /ZnWO 4 heterostructures were constructed using a simple hydrothermal synthesis method. The optimal composite ratio of catalytic materials was determined through photodegradation tests, and the best nanocomposite BiOIO 3 /ZnWO 4 heterostructure was obtained by varying experimental conditions such as the pH of the water and the concentration of pollutants. The optimal composite demonstrated good photocatalytic activity in all environments when TC was removed. The experimental results showed the finest sample, BOI/ZW-7, offers a lot of active sites for photocatalytic reactions because of its porous nature and big specific surface area. This composite exhibited excellent TC degradation across four different water bodies: deionised water, tap water, lake water, and rainwater, under simulated solar radiation. BOI/ZW-7's large surface area and porous structure enable abundant photocatalytic activity; under simulated sunlight, ≥60% TC removal (20 mg L −1 ) was reached within 100 min in deionized, tap, lake, and rain water. In summary, the constructed BiOIO 3 /ZnWO 4 heterojunction follows the conventional type II charge transfer mode, with h⁺ playing a major role in the photodegradation process. Under this feasible charge transfer pathway, the efficient degradation of TC in aqueous solution was ultimately achieved through effective carrier separation. Graphical This study employs a simple hydrothermal synthesis method to prepare a highly efficient photocatalyst based on a type-II heterojunction of BiOIO 3 /ZnWO 4 . ZnWO 4 nanorods are loaded onto the surface of BiOIO 3 nanosheets, forming a heterojunction to enhance the photocatalytic activity of the material.

Photocatalyst-based degradation of antibiotic pollutants is recognized as a promising strategy for wastewater treatment and solar energy conversion and utilization. The hydrothermal-ultrasound synthesized Mg-doped BiOCl/BiOIO 3 heterojunction (MBB) exhibits superior light-driven tetracycline (TC) degradation, achieving 87.69% removal in 60 min and outperforming pristine BiOCl and BiOIO 3 by 2.1- and 1.5-fold, enabled by band matching that suppresses charge recombination and improves carrier separation. Radical-trapping experiments reveal •OH and •O 2 ⁻ as the dominant reactive species responsible for TC photodegradation. Photocurrent response, electrochemical impedance spectroscopy (EIS), and fluorescence spectroscopy (PL) tests confirm that the MBB heterostructure has a faster migration rate of photogenerated carriers and a lower charge recombination rate. DFT calculations reveal that Mg doping shrinks the bandgap of BiOCl and optimizes the energy band arrangement of the heterojunction, thereby enhancing the light absorption capability. After five cycles, the MBB-0.2 (Mg-BiOCl/BiOIO 3 mass ratio 1:0.2) sample retains 76% degradation efficiency, without significant changes in phase and morphology, highlighting its stability for practical water treatment. This study attains the optimization of various photocatalysts through strategic doping and the construction of heterojunction structures, thereby maximizing the utilization rate of solar energy, providing a new research approach for the development of efficient solar conversion systems.

In this study, double S-scheme heterojunctions were constructed by a simple hydrothermal and calcination method, accompanied by the special layered structure of BiOIO3 employed for its I- modification. This resulted in the formation of CeO2/[Bi6O6(OH)3](NO3)3·1.5H2O (BHN)/I--BiOIO3, which possesses double S-scheme heterojunctions. The improvement of photocatalytic degradation efficiency is derived from the result of the synergistic effect of double S-scheme heterojunctions and I- modification. In photocatalytic degradation experiment with norfloxacin as the target pollutant, the degradation efficiency of typical sample (CeO2/BHN/I--BiOIO3-2) reaches 97.50%, which is 9 times and 1.6 times than that of pure CeO2 and BHN/BiOIO3, respectively. Obviously, the CeO2/BHN/I--BiOIO3 double S-scheme heterojunctions significantly enhances its photocatalytic degradation ability of antibiotics in comparison to single-substance photocatalysts and simple two-phase composite. It is noteworthy that the CeO2/BHN/I--BiOIO3 double S-scheme heterojunctions are also capable of achieving a degradation rate of up to 70% for norfloxacin in river water. Furthermore, this double S-scheme heterojunctions demonstrate the degradation efficiencies of approximately 90% for quinolone antibiotics, including ofloxacin, enrofloxacin, ciprofloxacin, and norfloxacin. This research offers a novel approach to enhance the photocatalytic degradation of organic pollutants through double S-scheme heterojunctions and elemental modification.

Aqueous Zn-ion batteries (AZIBs) recently have attracted broad attention. To achieve high energy density of AZIBs, constructing high-loading cathodes is the prerequisite. However, the cycling stability of high-loading cathodes still faces great challenges. Herein, a comprehensive strategy is proposed to improve the structural stability of the cathode material and mechanical stability of the high-loading cathode. The BiOBr@BiOIO 3 heterostructure are successfully constructed via sharing the interfacial oxygen atoms, in which the interfacial effect can effectively enhance the reaction dynamics and structural stability. Meanwhile, a biomimetic binder is skillfully designed via in situ dual cross-linking between guar gum and cation ions to achieve the application of water-based and sustainable polymer binder in AZIBs. Density functional theory calculations demonstrate the guar gum possesses strong affinity toward BiOBr@BiOIO 3 to firmly adhere the active materials. Quantitative nanomechanic technology visually demonstrates the robust mechanical properties of the as-obtained BiOBr@BiOIO 3 cathode. As a result, when the active material loading increases to as high as 100.71 mg cm −2 , an ultrahigh areal capacity of 20.02 mAh cm −2 can be achieved. Specially, a quasi-Ah-level (0.244 Ah) pouch-type cell with a loading of 1.17 g can be constructed, showing the practical application potential.

Antibiotic residues in aquatic environments pose a persistent threat to ecosystems and human health, necessitating efficient remediation strategies. This study presents a supramolecular-engineered type-II heterojunction that integrates β-cyclodextrin (β-CD) surface functionalization with a coral-like BiOIO3/β-Bi2O3 heterostructure for enhanced visible-light photocatalytic degradation of oxytetracycline hydrochloride (OTC). β-CD functionalization simultaneously extends visible-light harvesting through supramolecular sensitization and concentrates OTC molecules at the catalyst surface via host–guest inclusion complexation, which collectively accelerates interfacial charge-transfer kinetics. Concurrently, the staggered type-II band alignment between BiOIO3 and β-Bi2O3 promotes efficient spatial separation of photogenerated carriers, suppressing recombination. The optimized composite (2.5β-CD/BiOIO3/30β-Bi2O3) achieves 87.34% OTC degradation within 60 min, exhibiting a pseudo-first-order rate constant 2.87-fold that of pristine BiOIO3. Comprehensive characterizations confirm the heterojunction architecture and reactive oxygen species evolution. The catalyst exhibits satisfactory photostability after being used 4 times. Degradation pathways are elucidated via high-performance liquid chromatography-mass spectrometry (HPLC-MS), while density functional theory (DFT) calculations of electrostatic potential, Highest Occupied Molecular Orbital (HOMO), and Lowest Unoccupied Molecular Orbital (LUMO) distributions identify the preferential reactive sites of OTC, providing molecular-level mechanistic insight. This work decouples the synergistic contributions of surface supramolecular engineering and heterojunction band engineering, offering a design strategy for photocatalytic remediation of refractory pharmaceutical pollutants.
