Liquid metal electrodes are attractive in the field of energy storage due to their remarkable attributes such as high safety, cost effectiveness, extended lifespan, and high energy density. In this study, we develop a liquid bismuth–air battery owing to the advantageous oxygen ion conductivity offered by bismuth trioxide (Bi 2 O 3 ). Meanwhile, a Sb 2 O 3 –CuO–SnO 2 ceramic with corrosion resistance and stable conductivity in both reductive Bi and oxidizing Bi 2 O 3 are employed as the anode current collector. Impedance spectrum analysis and cross-sectional microscopic characterization are consistent with the formation of a heterogeneous Bi–Bi 2 O 3 architecture, which may provide mixed ionic–electronic conduction within the anode during discharge. This behavior, as inferred from morphological and electrochemical data, correlates with a volumetric specific capacity of 3580 mAh/cm 3 (94.6 % of the theoretical capacity) and an areal capacity of 2326 mAh/cm 2 under the tested conditions. The high areal and volumetric capacities, together with stable operation observed for >200 h in our tests, indicate the potential of liquid Bi–air batteries for high-density, high-temperature energy storage.

Aqueous supercapacitors possess high power density, long cycle life, and rapid charging and discharging capabilities, while their practical application is significantly limited by low energy density. The development of high-performance electrode materials, especially anodes, is crucial for enhancing the energy density of supercapacitor devices. In this work, Bi–Bi2O3 nanoparticles were anchored onto carbon fibers (Bi–Bi2O3@C) via a combined solvothermal and calcination process, using natural cotton to derive the biomass-derived carbon framework. The resulting Bi–Bi2O3@C composite was utilized as an anode material for aqueous supercapacitors, demonstrating excellent electrochemical performance with a specific capacity of 253.5 mAh g–1 (912.6 F g–1) at 1 A g–1. Furthermore, a high-performance cathode material composed of NiS2 nanoparticle-decorated Ni(OH)2 nanosheets (NiS2@Ni(OH)2) was prepared by a simple hydrothermal method to achieve optimal matching with the anode. The obtained NiS2@Ni(OH)2 nanosheets cathode composite displays high specific capacitance of 1984 F g–1 at 1 A g–1 and remarkable rate capability, retaining 57% of its original capacity even at a high current density of 10 A g–1. The constructed NiS2@Ni(OH)2//Bi–Bi2O3@C aqueous asymmetric supercapacitor (ASC) delivers a high energy density of 64.4 Wh kg–1 at a power density of 798.2 W kg–1, and maintains a high energy density of 43.1 Wh kg–1 even at a power density of 15.9 kW kg–1.

In order to develop low-cost photocatalyst, commercial Bi 2 O 3 was utilized as raw material to prepare α-Bi 2 O 3 /BiOCl core-shell heterojunction via a facile in situ chemical transformation method. To clarify experimentally the band alignment relationships between the α-Bi 2 O 3 and BiOCl (0 0 1), the α-Bi 2 O 3 /BiOCl (0 0 1) core–shell heterojunction band offsets were analyzed by X-ray photoelectron spectroscopy (XPS). Here based on energy gaps, valence band values of α-Bi 2 O 3 and BiOCl (0 0 1), core levels difference of Bi 4f in α-Bi 2 O 3 /BiOCl (0 0 1) heterojunction , we demonstrate that band alignment of ∼0.28 eV exists between α-Bi 2 O 3 and BiOCl with α-Bi 2 O 3 possessing the higher valence band potential or electron affinity which is a driving force of valence band holes from α-Bi 2 O 3 to BiOCl (0 0 1). While, the electrons in conduction band were driven to migrate through conduction band potential difference (0.49 eV) from BiOCl (0 0 1) to α-Bi 2 O 3 .

Nd 0.2 Ce 0.8 O 3-δ (NDC) is one of the most common solid electrolyte materials used in solid oxide fuel cells (SOFCs). However, the densification temperature of NDC electrolyte is above 1400 °C. In this work, Bi 2 O 3 and CoO sintering aids were individually or synergistically added to Nd 0.2 Ce 0.8 O 3-δ (NDC) electrolytes through the sol-gel method to lower its sintering temperature . Effects of Bi 2 O 3 -CoO dual sintering aid on the sintering behavior, phase composition, microstructure, and electrochemical properties of NDC electrolyte were all investigated. The data revealed that Bi 2 O 3 -CoO dual-sintering aid doped-NDC (labeled as NDC-CB) possessed high density and superior conductivity at low temperatures, better than that of Bi 2 O 3 or CoO single sintering aid. NDC electrolyte doped with Bi 2 O 3 -CoO dual-sintering aid achieved highest relative density of 95.3% at 1100 °C and total conductivity of 5.765 × 10 -2 S cm -1 at 800 °C. Furthermore, NDC-CB displayed excellent physical and chemical compatibility with La 0.6 Sr 0.4 Co 0.8 Fe 0.2 O 3-δ (LSCF) cathode and NiO-NDC anode. Oxygen reduction reaction at LSCF/NDC-CB interface was improved by about 40% when compared to NDC. In sum, Bi 2 O 3 -CoO looks promising as dual-sintering additive for lowing sintering temperature and increasing electrical conductivity of NDC. Therefore, NDC-CB might be potential electrolyte for future intermediate-temperature solid oxide fuel cells (IT-SOFCs).

Electrocatalytic CO 2 reduction (ECR) to high-value formic acid is an important approach for realizing carbon resource recycling and renewable energy storage. A key challenge in this process is the development of highly efficient and stable catalysts. In this work, three types of mesoporous catalysts, In 2 O 3 -ZrO 2 , SnO 2 -ZrO 2 , and Bi 2 O 3 -ZrO 2 , were prepared through a one-step method. The influence of type and existing state of active components on catalytic performance was researched in depth. These results indicate that the introduced active components exhibit a strong interaction with ZrO 2 support and exist as a highly dispersed state in the support. Among the prepared catalysts, the In 2 O 3 -ZrO 2 demonstrates superior activity and stability, achieving a formate Faraday efficiency of 90 % and a current density of 110 mA cm −2 at −1.17 V vs. RHE, while maintaining stable performance over an 80 h long-term ECR test. In addition, the mesoporous material with high specific surface area provides a greater number of active sites, thus contributing to the enhanced catalytic performance. This study provides a new catalyst synthesis strategy for ECR to formate and offers guidance for preparing high-efficiency catalysts.

In this paper, the novel 3D hollow Z-scheme heterojunction photocatalysts based on Bi 2 O 3 and CoAl layered double hydroxides (Bi 2 O 3 @CoAl-LDHs) were prepared for efficient visible-light-driven photocatalytic ammonia synthesis . The synthesized nanohybrid exhibits excellent photocatalytic ammonia synthesis performance (48.7 μmol·L −1 ·h −1 ) and structural stability , which is primarily attributed to the fact that Z-scheme heterojunction significantly enhanced lifetime of photogenerated carriers (6.22 ns) and transfer efficiency of surface photogenerated electrons (72.5%). Strict control experiments and nitrogen isotope labeling results show that nitrogen and hydrogen in the produced ammonia come from nitrogen and water in the reactant respectively. Electron paramagnetic resonance (EPR) experiments and density functional theory (DFT) calculations further reveal that the built-in electric field due to the difference between Bi 2 O 3 and CoAl-LDHs is the key to constructing the Z-scheme heterojunction. In addition, results of partial density of states (PDOS) show that Co in Bi 2 O 3 @CoAl-LDHs composite is the active site for photocatalytic N 2 fixation.

Private information protection of electronic chips which store large amounts of sensitive data, is a crucial issue in electromechanical systems nowadays. Here, a self-destructive microchip based on an instantaneous thermite reaction is designed to prevent the leakage of electronic information. The device is consisted of a silicon test wafer and an upper energetic film coated by a simple drop-casting technique. A series of Al/BiOX-based nanothermites have been prepared for decreasing the reaction sensitivity, meanwhile optimizing the destruction efficiency of the energetic film system. Among them, Al/Bi 2 O 3 nanothermite containing 30 wt% BiOBr possesses a low sensitivity (45 J), the maximum pressure peak (1.93 MPa) and pressure effect duration due to multiple interactions of the three nano-scale energetic components. Besides, the energetic film prepared by this nanothermite fomula also exhibits a more effective destruction of the device. The high-speed photography results demonstrate that the violent reaction shatters the thick energetic microchip (∼1 mm) within merely 0.5 ms. Importantly, the efficient destruction of energetic microchips shows excellent reproducibility in different working scenes, including Air or Ar atmosphere. It is believed that this self-destructive device with environmentally friendly components and simple but adaptive design can be extensively used in various electric microcomponents.

In this work, the electromagnetic of NiCuZn ferrite was enhanced and the sintering temperature was decreased by co-doped Bi 2 O 3 and Co 2 O 3 . The influence of the doping concentration of Co 2 O 3 on the microstructure and magnetic properties of NiCuZn ferrite was studied. Characterizations display that the high density and uniform microstructure of NiCuZn ferrite was obtained at a low sintering temperature of 925 °C. The Co ions were doped in the octahedral B-sites and decreased lattice constant and grain size. The resistivity was also improved after doping appropriate Co ions for the decrease of the Fe 2+ . The saturation magnetization, coercivity, permeability, and cut-off frequency were also enhanced after being doped with the Co 2 O 3 . Consequently, the NiCuZn ferrite doped with 0.30 wt% Bi 2 O 3 and 0.4 wt% Co 2 O 3 possesses a saturation magnetization of ~ 60.014 emu/g, coercivity of ~ 0.033 kA/m, real part of permeability of ~ 269.9 @ 1 MHz, and high cut-off frequency of 8.08 MHz, which can be applied in multi-layer chip inductors.

We present a strategy for the modification of an ion-exchange resin (D113) as an inexpensive carbon source to obtain a macrospherical photocatalyst precursor that can be transformed into a stable all-solid-state Z-scheme heterojunction catalyst (denoted Bi 2 O 3 -Co 3 O 4 @C). X-ray diffractometry and Fourier transform infrared and Raman spectroscopy measurements confirmed the presence of highly graphitized carbon in the complex. Significantly, the cost of the as-prepared material was only 1/200 of that of commercial carbon nanotubes and 1/80 of that of graphene oxide . Aided by the organic carbon source, Bi 2 O 3 -Co 3 O 4 @C showed an enhanced light absorption, hindered electron–hole recombination, and an enhanced photocurrent response. Under simulated solar irradiation, Bi 2 O 3 -Co 3 O 4 @C (20 mg/L) showed degradation efficiencies of 100%, 47.52%, 94.28%, and 100% for methylene blue, rhodamine B, tetracycline, and Cr(VI), respectively, after 120 min. Herein, the highest turnover frequency (TOF) obtained under irradiation was 2.5 h −1 for Cr(VI). Further, the degradation efficiency for methylene blue trihydrate remained 91.46% after five cycles, indicating significantly higher stability than that of a catalyst prepared without graphitic carbon. The optimized band structure and photocatalytic mechanism of Bi 2 O 3 -Co 3 O 4 @C were determined based on ultraviolet-visible measurements and plane-wave density functional theory calculations in VASP. The findings of this study indicate the promise of the Bi 2 O 3 -Co 3 O 4 @C macrospheres for industrial applications based on their photocatalytic performance, high stability, low cost, and suitable particle size.

Zinc–nickel battery attracts much attention because of their excellent rate performance and high operating voltage. However, their applications are strongly restricted by the poor cycling performance, which is caused by the degradation of the zinc anode during battery cycling. To overcome such limitation, a facile strategy to prepare homogeneously Bi 2 O 3 coated ZnO composites is proposed. The reaction is conducted in the liquid phase based on redox reaction of Bi 3+ and I − to directly grow BiOI on commercial ZnO powders, which are then converted to ZnO@Bi 2 O 3 by further heat treatment. Benefiting from the uniform Bi 2 O 3 coating, the solubility of ZnO is effectively reduced. The well-connected metallic Bi network is formed, which serves as the conductive substrate for uniform zinc deposition and hence inhibits the dendrites growth. The assembled zinc–nickel battery based on ZnO@Bi 2 O 3 composites exhibits significantly prolonged cycling life. Even under a high discharge current of 10 A (~ 138 mA cm −2 ), the battery can keep cycling during 400 cycles with discharge voltage higher than 1.1 V, which is extended by 3 and 1.7 times compared with that of electrodes based on pure ZnO and physical mixture of Bi 2 O 3 and ZnO. This work provides a facile strategy for synthesizing uniformly Bi 2 O 3 coated ZnO composites, which is helpful for large-scale synthesis of high-performance zinc anodes in practical application.

A coupling method of water surface plasma (WSP) with β -Bi 2 O 3 /CaFe 2 O 4 composite was applied to promote the elimination of aqueous Orange G (OG). The morphology, structures, crystal form and chemical bonding state of the prepared β -Bi 2 O 3 /CaFe 2 O 4 composite were characterized via SEM, TEM, EDS-mapping, XRD, FT-IR and XPS. The results showed that the addition of composites significantly enhanced the degradation and kinetic constant of OG. The degradation efficiency of the combined system containing 8.0 wt% β -Bi 2 O 3 /CaFe 2 O 4 composite was 28.9% higher compared to the sole WSP for OG degradation. The synergistic factor (2.387) demonstrated that the combined system was able to establish a synergistic effect. The effect including peak voltage, air flow rate, initial conductivity and initial concentration of solution on OG removal was inspected.

A new low-temperature magnetic Bi 2 O 3 -CoO-Fe 2 O 3 -B 2 O 3 (BCFB) glass was designed to acquire magnetic yttrium iron garnet (YIG/YIG) joint. This paper investigated the thermal behavior of BCFB glass and its wettability on YIG. The microstructural evolution, mechanical and electromagnetic properties of YIG/YIG joint were systematically studied. CoFe 2 O 4 nuclei were gradually formed, growing up into nano-scale CoFe 2 O 4 crystals in the glass seam. Meanwhile, some CoFe 2 O 4 crystals grew up excessively by swallowing nano CoFe 2 O 4 , reaching microns. YBO 3 reaction layer was formed and grew into YBO 3 whiskers at the interface of YIG/glass with the brazing temperature increasing. The joint shear strength increased, reaching a maximum of 85.2 MPa at 775 °C under the collaborative reinforcement of well-integrated interface and glass-ceramic seam, then declined due to the aggravative reaction. The dielectric constant of YIG/YIG joints decreased with the brazing temperature increasing, varying from 18.5 to 16.6 at the frequency of 10 MHz. AFM/MFM and VSM analyses indicate that the glass seam performed magnetic property. The saturation magnetization of BCFB glass reached about 4.2 emu/g and 5.0 emu/g heat-treated at 750 °C and 775 °C, respectively, which could effectively enhance the magnetism of the glass seam.
