Bismuth-based halide perovskites are semiconductors that respond well to light and can be used in reactions triggered by visible light. However, their structure makes them unstable in wet or aqueous conditions, limiting their use in water-based reactions. This paper presents a new method to create two moisture-resistant bismuth-based perovskites, (1,3-diethylbenzimidazole) 3 Bi 2 I 9 and (1-Methyl-3-ethyl-benzimidazole) 2 (1,3-diethylbenzimidazole)Bi 2 I 9 , by using N-methylbenzimidazole and N-ethylbenzimidazole with bismuth iodide. During this process, ethanol molecules in the solvent modify the N atoms at the 3-position of the benzimidazole molecules, with the help of hydroiodic acid, to form ionic liquids. The new perovskite materials do not contain alkali metal ions or organic ammonium ions, but rather ionic liquid cations (1,3-diethylbenzolamazole) + and (1-methyl-3-ethylbenzimidazole) + , thus giving them excellent moisturizing properties. The study also improves the photocatalytic performance of these materials by making them into micron-sized sheets using the anti-solvent method. Under visible light, the materials show high efficiency in reducing Cr(VI) (95.3 % and 92.3 % for the two materials) and producing hydrogen from HI splitting (2053.59 and 1957.76 μmol g −1 h −1 ). This research not only develops a method for creating moisture-resistant perovskites with ionic liquids but also shows potential for using these materials in photocatalytic reactions in water.

Bismuth-based materials that adhere to the alloy/dealloy reaction mechanism are regarded as highly promising anode materials for potassium-ion batteries due to their high volume-specific capacity and moderate reaction potentials. However, their commercial viability has been limited by the effects of structural collapse due to volume distortion and impeded electron conduction, resulting in rapid capacity decline. In this work, a carbon-coated nanosized BiPO4rod (BiPO4@C) was designed and fabricated to overcome the aforementioned challenges through the architecture engineering and anionic-tuning strategy. In particular, the nanosized nanorods significantly reduce the volume expansion; the incorporation of the bulk and open-skeleton anion PO43−serves to mitigate the considerable volume distortion and generates the high ionic conductivity product (K3PO4) to ameliorate the poor ionic transport due to the structural deformation. The elaborated BiPO4rods exhibit high specific capacity (310.3 mAh g−1, at 500 mA g−1), excellent cycling stability (over 700 cycles at 500 mA g−1) and superior rate performance (137.8 mAh g−1, at 1000 mA g−1). Systematic ex-situ XRD and TEM, as well as kinetic tests, have revealed the “conversion-multistep alloying” reaction process and the “battery-capacitance dual-mode” potassium storage mechanism. Moreover, the thick electrodes showed excellent specific capacity and rate performance, demonstrating their significant application potential in the next generation of SIBs.

The capturing and storage of iodine from nuclear waste through secure and advantageous techniques are significant. In this work, a novel bismuth-based porous carbon material referred to as Bi@MVF is elaborately synthesized employing a dipping-reduction technique to seize iodine-129 ( 129 I), in which bismuth particles are uniformly embedded and allotted on the porous carbon network as multiple active sites. Accordingly, Bi@MVF lets in a highly-efficient iodine absorption potential of up to 1560 mg/g after publicity to iodine at 120 ℃ for 4 h, superior to most standard iodine adsorbents. The excessive adsorption kinetics of these Bi@MVF adsorbents is typically attributed to the specific porous carbon substrates' full-size particular surface area and the adsorbent’s synergistic effect. An in-depth perception of the iodine adsorption mechanism exhibits that the chemical adsorption turns into a powerful mechanism via the reaction between bismuth and iodine to structure a steady section BiI 3 . Moreover, an easy post-treatment system for these Bi@MVF adsorbents is adopted to gain the greater corrosion-resistant iodine-binding segment Bi 5 O 7 I, attaining a nominal iodine leaching rate. Therefore, the designed Bi@MVF will be a tremendous 129 I stabilizer, and we will contribute a new approach for customizing new iodine adsorbents with excessive adsorption doses.

Because of their non-toxicity and low cost, bismuth-based materials have received considerable attention for the capture of gaseous iodine, especially for the removal of radioactive iodine in nuclear post-processing plants. In the actual operation conditions of reprocessing plant, the presence of water vapor must be considered as an important factor because it will significantly affect the iodine capturing efficiency for most iodine-capturing materials. To address this problem, we successfully synthesized a hydrophobic bismuth-based chrysotile membrane, which was modified by the silane coupling agent KH570. The chrysotile fiber was chosen to provide rich reactive sites for bismuth loading, and the bismuth was chosen due to its high affinity to iodine. The hydrophobic surface endowed by KH570 acts as a ‘protecting layer’ when water vapor exists during iodine adsorption. The maximum of iodine capture efficiency of the prepared membrane reached 483.37 mg/g in air, and 443.04 mg/g under 75 % relative humidity. Comparing hydrophobic membrane with one that non-modified by KH570, the hydrophobic membrane increases about 54 % iodine adsorption capacity in humid condition. This study provides a certain reference value for the application of bismuth-based materials in iodine removal under humid conditions.

Sodium (Na) metal anode has been considered as the promising candidate for next generation high-energy-density rechargeable batteries such as Na-S, Na-O 2 and Na-CO 2 , owing to its high specific capacity, low electrode potential and low cost. Unfortunately, some intractable problems hinder the practical application, including volume change and dendrite formation induced by inhomogeneous Na nucleation. Herein, 3D carbon cloth (CC) supporting Bi-MOF derived carbon nanosheets containing Bi nanoparticles and carbon shells (CC@Bi@C) were prepared to serve as Na deposition/dissolution hosts, integrating high surface area and favorable sodiophilicity. Due to the existence of Bi sodiophilic sites, Na nucleation and deposition can be induced, rendering uniform and dendrite-free morphology. Moreover, the 3D carbon framework can effectively reduce the current density and uniform distribution of Na + flux, solving the uncontrolled Na dendrite growth. As a result, the CC@Bi@C||Na half cell operating at 1 mA cm −2 for 1 mA h cm −2 exhibits 99.85% Coulombic efficiency for nearly 500 cycles. The symmetric cell maintains stable cycle for more than 300 h at 2 mA cm −2 for 2 mA h cm −2 with low overpotential. When paired a full cell with Na 3 V 2 (PO 4 ) 3 cathode, CC@Bi@C anode exhibits a stable capacity of 103.4 mA h g −1 at 1C (1 C = 117 mA h g −1 ) over 150 cycles for 95.5% capacity retention with high CE of 99.0%. This work provides a facile strategy to inhibit dendrite growth and uniform Na deposition.

Radioiodine is one of the main fission products in the nuclear industry. Due to its strong volatility and radiotoxicity, it must be filtered and purified before being released into the environment. In this work, we reported three novel bismuth-based iodine sorption materials coated with Bi and/or Bi 2 O 3 on the surface of electrospinning carbon nanofibers (HT-Bi 2 O 3 -ESCNF, HT-Bi-Bi 2 O 3 -ESCNF and HT-Bi-ESCNF). These materials were obtained by adding a hydrothermal step on the basis of electrospinning, pre-oxidation and carbonization process. The benefit of hydrothermal load was that active sites appeared on the outer surface of the fiber, making the contact with iodine gas more convenient and effective, and was no longer restricted by the concentration of Bi 3+ in the solution like before. Finally, iodine capture tests were also conducted on these three sorbents and the property changes were investigated before and after iodine exposure. The results showed that the coating on the surface of the fiber did greatly improve the iodine capture capacity, and elemental bismuth had a greater effective atomic utilization rate of iodine than bismuth oxide, whose sorption capacity reached a record high of 732 mg/g among all the bismuth-based sorbents. The capture mechanism was thoroughly elucidated by a combination of PXRD, SEM, TEM, BET, XPS, Raman spectra and TGA characterizations.

Developing bismuth-carbon composites that can alleviate the stress concentration and volume expansion problems during the Bi/BiOCl conversion reaction is crucial for electrochemical desalination, especially Cl − removal technology, but it is still a great challenge. Here, we report a B/N co-doped bismuth encapsulated in carbon tubes. Using CAU-17 as a template, a carbon tubular material with multiple carbon layer structures was successfully synthesized by co-pyrolysis with BCN nanosheets, which achieved effective encapsulation of Bi. As the pyrolysis temperature increased, the continuous evaporation of Bi prompted the transformation of the carbon tube structure from a soft carbon to a hard carbon structure interconnected by multi-layered short graphene flakes. This alleviated the instability of the electrode caused by the volume expansion during the Bi/BiOCl transformation reaction and also provided additional ion storage capacity. When applied to the CDI dechlorination anode, Bi@BCN-900 exhibited a high desalination capacity of 145.96 mg g −1 and low energy consumption of 0.53 kWh kg −1 NaCl at an applied voltage of 1.2 V. Moreover, Bi@BCN-900 showed good stability over long-term cycling tests. This work expands the application of CAU-17 and offers new research insights for the design of bismuth-based materials for CDI dechlorination anodes.

Comprehensive Summary In recent years, the anode materials of bismuth(Bi)-based potassium ion batteries with high theoretical capacity and suitable potassium ion insertion potential have attracted extensive attention. However, due to the volume expansion of Bi, the performance of Bi-based anode materials is not ideal during potassium ion (de)intercalation. In order to solve these problems, we report a three-dimensional (3D) ternary bismuth nanoparticles/conductive polymers/carbon nanotubes (Bi/PPy/CNT) hybrid anode material for K-ion batteries. At a current density of 100 mA·g –1 , its reversible capacity reaches 302 mAh·g –1 after 200 cycles, while it reaches 195.7 mAh·g –1 after 600 cycles at 1 A·g –1 . Its excellent performance is attributed to the hydrogel network which provides a range of electron transport networks and high porosity. Carbon nanotubes are used as electron enhancers to reduce the volume expansion of Bi particles during the reaction. This study provides a prerequisite for expanding the application of 3D ternary materials.

The electrochemical reduction of carbon dioxide (ERCO2) to formate with high selectivity has been considered a promising strategy to overcome the energy and environmental crises. Bi-based materials present good application prospects, but the development of a new class of electrocatalysts with high performance remains a challenge. Herein, a novel topological chemical transition strategy is developed to rationally design highly active Bi-based materials, which are a new representative of Bi-based electrocatalysts for ERCO2. Bismuth oxysulfate (Bi2O2SO4) is prepared by a simple topological transition from the Bi2S3 precursor in air, which can further topologically transform into the metal Bi by a fast reduction treatment of NaBH4 solution. This kind of Bi2O2SO4 exhibits superior catalytic performance for ERCO2. The maximum Faraday efficiency (FE) of HCOO− is up to 97% at −0.9 V vs. RHE in an H-type cell. A high FE > 90% in a wide potential range of −0.5 to −1.2 V and a large current density of 319 mA cm−2 at −0.8 V can further be realized in a flow cell. The post-characterization studies and density functional theory (DFT) calculations confirm that the Bi2O2SO4 derived Bi catalyst has an optimal (104) plane to realize the optimized free energies of OCHO* and H* reaction intermediates, leading to superior catalytic activity over the NaBH4 derived Bi sample. Our work put forward a promising strategy to exploit advanced electrocatalysts for electrolysis.

Discovering bismuth based smart materials that can respond to thermal, mechanical, and wide range X-ray to infrared photon excitation remains a challenge. Such materials have various uses like in advanced information encryption . In this work, valence state change between Bi 2+ , Bi 3+ , and Bi 4+ , and the dual role of Bi 3+ in trapping electrons and holes have been studied in Bi 3+ or/and Ln 3+ (Ln=Tb or Pr) doped LiScGeO 4 family of compounds by vacuum referred binding energy (VRBE) diagram construction, thermoluminescence , and spectroscopy. Electron release from Bi 2+ has been evidenced. It can be used to experimentally determine the VRBE in the Bi 2+ 2 P 1/2 ground state and to realize Bi 3+ negative quenching luminescence . Particularly, a new force induced charge carrier storage phenomenon has been discovered for non-real-time force recording. Wide range of emission tailorable afterglow , unique Bi 3+ ultraviolet-A, white, and infrared afterglow have been demonstrated by using Bi 3+ as a hole trapping and recombination center and using energy transfer processes from Bi 3+ to Tb 3+ , Pr 3+ , Dy 3+ , or Cr 3+ . Proof-of-concept advanced anti-counterfeiting, information encryption, and X-ray imaging will be demonstrated. This work not only develops smart storage phosphors , but more importantly unravels the valence change between Bi 2+ , Bi 3+ , or Bi 4+ and how it can affect the trapping and release of charge carriers with thermal, optical, or mechanical excitation. This work therefore can promote the discovery and development of Bi 3+ based smart materials for various applications.

Perfluorooctanoic acid (PFOA) is highly stable due to the strong C F bond and extremely difficult to be removed by conventional photocatalysts. In this study, Bi doped BiOI 1-x F x solid solutions with hollow microsphere structure were prepared through a facile one-step hydrothermal method. Compared with pure BiOI and BiOF, the band gap of the Bi/BiOI 1-x F x solid solutions was significantly reduced, thus promoting the visible light absorbance. The cavity structure of the BiOI 1-x F x solid solutions enhanced the surface areas and active sites for reaction. The local electromagnetic field dominated by surface plasmon resonance (SPR) effect of Bi metal on the surface favored the separation of the photoinduced charge pairs. As a consequence, Bi/BiOI 0.8 F 0.2 (x = 0.20, the doping amount of fluorine was 20 %) composite displayed the best photocatalytic performance for decomposing PFOA, and 40 mg/L PFOA could be removed within 2 h illumination. The degradation rate constant (k = 0.0375 min −1 ) of PFOA by Bi/BiOI 0.8 F 0.2 was about tenfold of that by pure BiOI and BiOF. Superoxide radical ( · O 2 -) predominated in the degradation of PFOA by Bi/BiOI 0.8 F 0.2 , and the possible degradation pathway of PFOA by Bi/BiOI 0.8 F 0.2 was proposed. This work provides a highly efficient catalyst for the practical application in removal of highly persistent PFOA.

The bismuth-based materials are proven as valid electrocatalysts for electrochemical conversion of carbon dioxide (CO2) into formate (HCOO−). Herein, we discover that HCO3− can destroy the Bi–O bonds of the bismuth–carboxylate MOF to achieve in situ transformation into Bi2O2CO3 (MOF-derived Bi2O2CO3), which is merely explored yet. MOF-derived Bi2O2CO3 shows superior electrocatalytic performance in a broad range of potentials and demonstrates a formate faradaic efficiency (FEHCOO−) of 96.1% as well as an outstanding durability in 48 h with a current density about 10 mA cm−2 at a potential of −0.669 V vs. RHE. And compared with the structurally similar bismuth oxyhalides, MOF-derived Bi2O2CO3 possesses higher stability and lower CO2 concentration-dependence during CO2 reduction. Furthermore, this work puts a new strategy forward to achieve in situ MOF transformation and to comprehend the stability of electrocatalysts.
