The first rare earth metal iodate fluoride, Ce(IO 3 ) 2 F 2 ⋅H 2 O, was synthesized by a hydrothermal method. In the structure, CeO 5 F 4 polyhedra connect with isolated IO 3 groups to form 1D infinite [Ce(IO 3 ) 2 F 2 ] chains, which interconnect with each other by weak hydrogen bonds to construct the whole structure. Ce(IO 3 ) 2 F 2 ⋅H 2 O produces a large second harmonic generation response, which is three times that of potassium dihydrogenphosphate. Theoretical calculations with DFT and dipole moments were performed to illustrate the relationships between the structure and the properties. The results show that Ce(IO 3 ) 2 F 2 ⋅H 2 O is a new iodate fluoride with novel structure and potential applications in nonlinear optics. Graphical Highly responsive : The first rare earth metal iodate fluoride, Ce(IO 3 ) 2 F 2 ⋅H 2 O, which was synthesized by a hydrothermal method, exhibits a large second harmonic generation response, which is three times that of potassium dihydrogenphosphate (KDP; see figure).

In this study, manganese oxide-supported catalysts (MnO x @SiO 2 ) were synthesized by co-precipitation with a subsequent high-temperature calcination and employed to activate periodate (PI) for the degradation of bisphenol A (BPA). The MnO x @SiO 2 –500 system exhibits optimum PI activation performance with an associated 96.0 % BPA degradation efficiency outperforming MnO x . The MnO x @SiO 2 –500/PI system was subjected to comprehensive analysis, including electrochemical tests, quenching experiments, electron spin resonance (ESR), methyl phenyl sulfoxide (PMSO) probe experiments, Mn ion leaching detection, UV–vis spectroscopy, and X-ray photoelectron spectroscopy (XPS). The results revealed that BPA degradation is promoted by a MnO 2 -PI ⁎ complex via homogeneous activation in solution and iodate radicals (IO 3 • ) involving heterogeneous activation. In the case of the homogeneous activation, Mn(II) undergoes a two-electron transfer to form MnO 2 , which is complexed with PI to generate MnO 2 -PI ⁎ . In the heterogeneous activation, Mn 3 O 4 on the surface of MnO x @SiO 2 –500 activates PI to produce IO 3 • . Based on high-performance liquid chromatography-mass spectrometry (HPLC-MS) and density functional theory (DFT) calculations, three possible BPA degradation pathways are proposed. In pathways I and II, the active species attack C atoms on the two BPA benzene rings to initiate hydroxylation and oxidation. In pathway III, the attack generates a C C bond, yielding multiple degradation intermediates bearing a benzene ring. In addition, the acute and chronic toxicities of by-products with respect to aquatic organisms are predicted using the ECOSAR software. The majority of degradation intermediates exhibit lower toxicity than the starting BPA. This study provides a green and efficient strategy for BPA removal in wastewater treatment.

In this work, we report the efficient removal of I − /IO 3 − from wastewater by tripropylamine quaternary ammonium cation based monodisperse microspheres. Benefitting from the rapid solvent exchange process and the excellent ionic selectivity of tripropylamine quaternary ammonium cation, these microspheres show capture rate of 98% for I − and 66% for IO 3 − at a concentration of 50 ppm. Meanwhile, they exhibit high adsorption capacities of 350 mg/g for I − and 370 mg/g for IO 3 − , coupling with excellent reusability. These characteristics highlight their superior practicability for removal of iodine, particularly in the context of radioactive iodine-contaminated water.

Herein, we reported two alkali metal molybdenum(VI) iodates, namely, NaMoO 3 (IO 3 ) and γ-KMoO 3 (IO 3 ) with 1D and 3D [MoO 3 (IO 3 )] − anionic architectures, respectively. The novel 1D chain in NaMoO 3 (IO 3 ) and the 3D network in γ-KMoO 3 (IO 3 ) are constructed by the 0D Λ-shaped cis -[MoO 4 (IO 3 ) 2 ] 4− building units interconnected by bridging IO 3 − anions as well as the corner-sharing of oxo anions. Importantly, the polar γ-KMoO 3 (IO 3 ) exhibits a very large second-harmonic generation (SHG) effect of 12 × KH 2 PO 4 (KDP) under 1064 nm laser radiation, a high laser-Induced damage threshold value (52 × AgGaS 2 ), and a moderate birefringence of 0.087@1064 nm, whereas the centrosymmetric NaMoO 3 (IO 3 ) has a large birefringence of 0.208@1064 nm. This study further proves the useful route of exploring promising optical materials via assembling the 0D basic building units into higher dimensional anionic architectures.

The efficient capture and immobilization of radioiodine (I–, IO3–) is of great importance in radioactive waste management. Here, a Cu2O-loaded three-dimensional bulk cationic hydrogel composite (Cu2O@CH) was successfully prepared by simple redox reactions and UV photopolymerization, which realized the rapid enrichment and efficient immobilization of I– and IO3–. The adsorption experiments showed that the maximum adsorption capacity of Cu2O@CH for I– in the solution at pH = 3 reached 416.5 mg/g, and the adsorption capacity of IO3– in the solution at pH = 6 could reach 313.4 mg/g. It exhibited extremely fast adsorption kinetics for I– and IO3–. In addition, Cu2O@CH also exhibited efficient I– and IO3– removal from simulated high-level liquid waste. The rapid capture and effective immobilization of radioiodine (I–, IO3–) were realized by the electrostatic interaction of −N+(CH3)3 groups in Cu2O@CH with I– and IO3–, as well as the chemical reactions between Cu2O and I–. The bulk cationic hydrogel composite explored the multifunctional role toward fast, high adsorption capability and easy handling, highlighting its superiority compared to the powder adsorbent, which renders it a potential adsorbent for the removal of radioactive iodine (I–, IO3–) in nuclear wastewater treatment.

A new alkali-metal iodate, K6(IO6H4)(HI2O6)(HIO3)2(IO3)4·2H2O (KIOH), was successfully grown at room temperature by a slow evaporation method. To our knowledge, the title compound is the first alkali-metal iodate containing isolated [I5+O3] and [I7+O6] units in one structure. Both the bond valence sum and X-ray photoelectron spectroscopy confirmed this phenomenon, which is consistent with the single-crystal data. Also, the theoretical calculation results showed that the title compound is a potential birefringent material. What is more, the low-cost growth of centimeter-sized crystals for the title compound greatly enriches the structural chemistry of the iodate system.

The balance between band gap and second harmonic generation (SHG) response, which are usually inversely related, is the key factor for achieving good performance in a mid-infrared (mid-IR) nonlinear optical (NLO) crystal. Still it remains a challenge to achieve this balance, which strongly hinders the development of mid-IR solid-state lasers. In this work, utilizing an aliovalent substitution strategy of functional units, we successfully realize mid-IR NLO balanced performance in a chiral iodate, Ga(IO3)3, which simultaneously exhibits a strong SHG response (13 × KDP) and a wide optical band gap (3.94 eV). The first-principles calculation is also performed to elucidate its NLO origin. Combining the experimental measurements and theoretical calculations, it is clear that Ga(IO3)3 possesses excellent comprehensive NLO performance including a strong SHG effect, a wide band gap, good thermal stability (450 °C), and a large birefringence, indicating its potential applications as a mid-IR NLO crystal.

“Amphiphilic” carbon dots (A-CDs) with a strong green fluorescence emission were synthesized by a simple and green method at room temperature. The characterization demonstrated that the synthesized A-CDs have both hydrophilic and hydrophobic properties and could be dispersed well in aqueous and organic solutions. As a fluorescent probe, the fluorescence of A-CDs could be obviously quenched in the presence of iodine (I2) and the quenching rate is proportional to the concentration of I2. Therefore, the A-CDs could be used as fluorophores for the detection of I2 with higher selectivity and sensitivity, and the linear working range for the I2 sensor is 80 nM–10 μM with a detection limit of 3.5 nM (S/N = 3). More interesting is that IO3− and I− could be transformed to I2 with different sample treatment processes, therefore, the I2 sensor based on A-CDs could also be used for the analysis of iodine species (I2, I− and IO3−) in samples. The possible mechanism has also been discussed in this work, and the high selectivity response to I2 can be attributed to the amphiphilic properties of A-CDs, which bring I2 closer to A-CDs and quench their fluorescence. The proposed I2 sensor has been successfully used for the analysis of iodine species in highly saline water, and the satisfactory results of detection and analysis of iodine species in samples demonstrate that the developed I2 sensor based on A-CDs has potential application in the fields of environment and clinical medicine.

Advancements in wearable electronics have driven demand for flexible, self-powered UV photodetectors, yet the efficient separation and transport of carriers remain critical challenges to realizing their full potential. This study constructs a high-performance flexible self-powered UV detector based on an electrochemically doped Bi-ZnO nanoflowers/PEDOT-CH 2 OH p-n heterojunction, further modified with a Co(IO 3 ) 2 layer. Bi 3+ doping introduces oxygen vacancies to enhance carrier separation, synergizing with the built-in electric field within the heterojunction. The spontaneous polarization of Co(IO 3 ) 2 enhances this electric field, optimizing band alignment and suppressing recombination, while hydroxyl groups in PEDOT-CH 2 OH stabilize the oxygen vacancies. The piezoelectric response of ZnO is not prominent in this device, as its modulating effect is overshadowed by the dominant charge separation mechanism based on doping and interfacial polarization. Through synergistic bandgap engineering, defect control, and interface modification, the optimized device achieves a responsivity of 2.05 mA/W, a specific detection rate of 3.25 × 10 10 Jones, and an ultrafast response time of 54 ms under 365 nm UV illumination. The detector exhibits exceptional flexibility, stability, and selectivity, maintaining high performance through 2500 bending cycles, indicating significant potential for application in flexible, wearable UV sensing.

Graphical A visible-light-responsive photocatalyst based on nitrogen-doped bulk oxide YTaO 4− x N y was synthesized and used as an H 2 evolution photocatalyst for Z-scheme overall water splitting coupling with the PtO x /WO 3 as the O 2 evolution photocatalyst and the I − /IO 3− as the shuttle ions. Nitrogen doping into oxide has been proved to be an effective strategy to extend visible-light utilization of oxides with layered or channeled structure, but it is shortage for the bulk oxides free of layered or channeled structure. Here, we report a novel nitrogen-doped bulk oxide (denoted as YTaO 4− x N y ) with good visible light response. As benefited from the strong hybridization of N 2 p and O 2 p electronic state according to the density functional theory (DFT) calculations, the band gap (3.6 eV) of YTaO 4 precursor was sharply narrowed to 2.4 eV on YTaO 4− x N y due to the obvious uplift of the valence band maximum (VBM). After decorated with the platinum cocatalyst, the Pt/YTaO 4− x N y was used as the H 2 -evolving photocatalyst for assembly of Z-scheme overall water splitting system by coupling with the PtO x /WO 3 as the oxygen evolution photocatalyst and using the I − /IO 3− as the shuttle ions. This work enriches the material database of nitrogen-doped oxide with wide visible light absorption and shows its promising application in solar-to-chemical conversion.

Exploration of new iodates is crucial due to their splendid applications in the nonlinear optical (NLO) field. Two new IIIA metal iodate–selenates, namely, [M(OH)2]3(IO3)(SeO4)·H2O (M = Ga and In), have been successfully synthesized using the hexagonal tungsten oxide (HTO) framework as an ideal structural template. Isostructural [M(OH)2]3(IO3)(SeO4)·H2O (M = Ga and In) crystallize in the polar space group P63mc. Their structures feature ∞[MO2(OH)2]3− (M = Ga, In) layers composed of corner-shared circular M3O6(OH)9 trimeric units based on MO2(OH)4 octahedra. The SeO4 groups are capped above half of the trimeric units of the layers while the IO3 groups are capped below the remaining trimeric units of the layers. Both compounds exhibit moderate phase-matchable second-harmonic generation (SHG) responses (2.9× and 3.8× KH2PO4) under 1064 nm laser radiation and the same band gap of 3.38 eV. Results of theoretical calculations revealed that their SHG effects originated from the synergistic effect of MO6, IO3 and SeO4 groups. So far reports on iodate–selenates are scarce and this work provides a new perspective to design new NLO materials through polar HTO-type topologies and a mixed-anionic strategy.
