Capacitive deionization (CDI) is perceived as a promising technology for freshwater production owing to its environmentally friendly nature and low energy consumption. To date, the development of high-performance electrode materials represents the foremost challenge for CDI technology. In this work, the porous bismuthene/MXene (P-Bi-ene/MXene) heterostructure was synthesized using a simple interfacial self-assembly method with two-dimensional (2D) bismuthene and Ti 3 C 2 T x MXene . Within the P-Bi-ene/MXene heterostructure, the porous structure can increase the active site and facilitate ion transport. Simultaneously, MXene effectively enhances the conductivity of the heterostructure, resulting in accelerating electron transport. Due to these attributes, the P-Bi-ene/MXene heterostructure demonstrates high desalination capacity (90.0 mg/g), fast desalination rate, and good cycling performance. The simple self-assembly strategy between 2D/2D materials described herein may offer inspirations for the synthesis of innovative electrode materials with high performance.

Developing high-performance electrocatalysts for CO 2 reduction reaction (CO 2 RR) is vital in achieving a carbon-neutral society by converting CO 2 into valuable chemicals. CO 2 RR electrocatalyst with lower overpotential, higher selectivity and wider working potential range is urgently desired, but it is still challenging to realize these factors simultaneously. Here, high-performance bismuthene-based electrocatalysts were synthesized by reducing bismuth precursors like BiCl 3 , BiBr 3 , and BiI 3 in liquid phases. Especially, bismuthene-I derived from BiI 3 showed a nanosheet morphology (around four-layer) with significantly enhanced (110) surfaces. It enabled an ultrawide potential window (0.7 V) for high formate selectivity (>90%) in a H-type cell and achieved an ultralow potential (−0.46 V vs. reversible hydrogen electrode) to attain a current density of 200 mA cm −2 in a gas-diffusion flow cell. The prominent long-term operational capability of bismuthene-I was demonstrated in both H-type and gas-diffusion cells. Density functional theory calculations revealed that bismuthene-I possessed abundant topological Bi(110) surfaces states that can reduce the CO 2 RR overpotential, suppress the competitive hydrogen evolution reaction, and facilitate electron donation during CO 2 electrocatalysis. The bismuthene-I realized low overpotential, high selectivity and wide working potential range simultaneously for electrochemical CO 2 RR. This work unfolds the broader plausibility of facilely reducing precursors for the scalable fabrication of high-performing CO 2 RR electrocatalysts.

In a biomimetic iontronic electrochemical system, the interior ions can move accompanied by surrounding charges, and then facilitating the integral carrier transfer, yet their transfers are still restricted by concentration gradient and temperature. Here, an ordered porous bismuthene electrode is designed, composed by bismuthene, bismuthene-derived Bi 2 O 3 &BiOCl, and borophene materials, with supercapacitive 4.96 F g −1 attribute retaining 89.6 % after 29,600 cycles, and the dispersive bismuthene nanosheets are also embedded into regenerated silk fibroin as elastic electrolyte. The resultant symmetrical iontronic pressure sensor shows high sensitivity of 2.31 kPa −1 in a wide 0.2–10 kPa range, and 0.41 kPa −1 sensitivity ranging 10–48 kPa, fast response/recovery time of 60/50 ms, and low detection limit of 0.45 Pa. The simulation and mechanism analysis demonstrate that a field emission effect plays an important role in electrolyte, in which the ions around the ordered bismuthene as emitters are launched and moved along the inner bismuthene nanosheets, step by step, to enormously shorten the ions migration path and effectively accelerate ion-charge pair transfer. Compared to the device without bismuthene in electrolyte, the sensitivity of sensor is improved by 23.81 times with high reproducibility over 1000 cycles. Additionally, the poly (3, 4-ethylenedioxythiophene): poly (styrene sulfonate) in electrolyte effectively constrains the movements of polymer molecules, contributing to high temperature adaptability from −15 to 70 ℃. In practical application, a tiny pressure monitoring in hot/cold perception is demonstrated, revealing a promising application in wearable systems and intelligent robotics.

Bismuth has a great potential as an anode for PIBs, due to its layered structure with a large interlayer spacing, long mean free path, high volumetric capacity (3800 mA h L−1) and environmental friendliness. Bismuthene, a 2D-layered structure, can be exfoliated from bismuth by mechanical or chemical methods. The unique structure of bismuthene is beneficial to the diffusion of potassium, penetration of the electrolyte, and buffering of the volume change along the c-axis, which will boost the anode performance of PIBs. An ultrasonication-assisted electrochemical exfoliation method was proposed in this study to prepare ultra-thin few layered bismuthene nanosheets (FBNs) simply and quickly. The as-prepared FBNs were employed in KIBs as an anode and delivered highly stable capacities of 423, 356, 275 and 227 mA h g−1 at the current densities of 2.5, 5, 10, and 15 A g−1, respectively. There was no obvious decay over 2500 cycles with a capacity of over 200 mA h g−1 at 20 A g−1, realizing excellent rate-capability and long-term cycling stability in KIBs. Furthermore, the mechanism of the excellent electrochemical performances was elucidated via in-depth characterization and theoretical calculations. This work provides a new strategy to prepare scalable ultra-thin nanosheets, which act as a promising candidate for the anode in energy storage systems.

The CO2 photoreduction process is becoming a promising strategy to solve the energy shortage problem and global warming in recent years. How to promote the separation of photoinduced carriers has attracted attention for the improvement of photocatalytic CO2 reduction. In the present work, an S-scheme heterojunction of Bismuthene/CsPbBr3 quantum dots (Bismuthene/CsPbBr3 QDs) is constructed as the photocatalyst for CO2 conversion. As a result, Bismuthene/CsPbBr3 QDs exhibit an optimal CH4 evolution rate of 43.1 μmol h–1 g–1 with 84.53% selectivity over CH4 under ultraviolet–vis light (UV–vis) irradiation. Construction of the S-scheme heterojunction with a narrow band gap semiconductor is the main factor for improving the photocatalytic performance, as the S-scheme heterojunction can suppress the recombination of photoinduced carriers and retain redox ability. The narrow band gap semiconductor Bismuthene can enhance light absorption abilities. This work probably provides some insights for the designing of heterojunction photocatalysts and the improvement of photocatalytic performance.

The rediscovery of black phosphorus (BP) has expanded the 2D family into Group 15 (Nitrogen Group) elements, among which bismuthene is the latest member with extraordinary opto-electronic, catalytic and biocompatible properties and potential as a 2D topological insulator. However, bulk Bi is not easily mechanically exfoliated as its counterpart of BP. Thus, to date, the reports on 2D Bi fabrication are rare, and investigations on its nonlinear optical properties are even less. Herein, we rationally designed a new strategy combining acid-interaction and liquid exfoliation to successfully transform metal bulk Bi into few-layer semiconductor, which resulted in unseen opto-electronic properties, such as tunable nonlinear responses all the way to the near-infrared (NIR) region. This band is critical for telecommunication and military purposes, but currently, functioning materials are extremely scarce. The origin of this strong saturable absorption was thoroughly explored through time-resolved spectroscopy spanning from the fs to μs timescale, which indicated ultrafast fs to ps carrier dynamics in the early stage and long exciton bleaching recovery up to μs. As a proof-of-concept application, the as-prepared 2D Bi was employed as a saturable absorber to mode-lock a Tm-doped fiber laser and successfully realized a 2 μm NIR-wavelength output. This study not only offers an effective and scalable method to fabricate the new 2D family member bismuthene with extraordinary stability, but also explores its strong and broad nonlinear responses extending into the NIR region and fundamental photoinduced dynamics, which demonstrate the full potential of 2D Bi for application in opto-electronic devices and nonlinear optics.

Capacitive deionization has been considered as a promising solution to the challenge of freshwater shortage due to its high efficiency, low environmental footprint, and low energy consumption. However, developing advanced electrode materials to improve capacitive deionization performance remains a challenge. Herein, the hierarchical bismuthene nanosheets (Bi-ene NSs)@MXene heterostructure was successfully prepared by combining the Lewis acidic molten salt etching and the galvanic replacement reaction, which achieves the effective utilization of the molten salt etching byproducts (residual copper). The vertically aligned bismuthene nanosheets array evenly in situ grown on the surface of MXene, which not only facilitate ion and electron transport as well as offer abundant active sites but also provide strong interfacial interaction between bismuthene and MXene. Benefiting from the above advantages, the Bi-ene NSs@MXene heterostructure as a promising capacitive deionization electrode material exhibits high desalination capacity (88.2 mg/g at 1.2 V), fast desalination rate, and good long-term cycling performance. Moreover, the mechanisms involved were elaborated by systematical characterizations and density functional theory calculations. This work provides inspirations for the preparation of MXene-based heterostructures and their application for capacitive deionization.

Electrochemical reduction of CO 2 to high-value chemical feedstocks, such as formate, is one of the most promising ways to alleviate the greenhouse effect. Unfortunately, the exploration of electrocatalysts with high activity and selectivity over a wide potential window (especially low potential for high current density) still remains a grand challenge. In this study, the fabrication of bismuthene nanosheets using an in-situ electrochemical transformation strategy of monoclinic scheelite BiVO 4 flakes is demonstrated. Catalyzing the CO 2 electroreduction in 1 m KHCO 3 aqueous solution, the bismuthene nanosheets exhibit a dramatically high formate Faradaic efficiency (FE) of ≈97.4% and a very large current density of −105.4 mA cm −2 at −1.0 V versus reversible hydrogen electrode. Significantly, over a record wide potential window of 750 mV from the initial −0.65 V to the applied minimum −1.4 V, the formate FEs of the bismuthene nanosheets are always higher than 90%, outperforming state-of-the-art electrocatalysts. Both experimental and theoretical investigations reveal that, in comparison with • COOH and H • intermediates, the bismuthene nanosheets preferentially promote fast reaction kinetics towards HCOO • , which eventually accelerates the production of formate.

Bismuthene nanosheet is a nontoxic and low-cost two-dimensional material, and has been reported with very limited biomedical applications. In this report, for the first time, we reported the utilization of bismuthene nanosheet for combined photothermal, photocatalytic and chemotherapy for cancer treatment. Partially oxidized bismuthene nanosheet was modified with polyethylene glycol (POBNS-PEG) and used as a drug delivery vehicle for the first time (antitumor drug doxorubicin (DOX) was used as a model drug, POBNS-PEG/DOX). POBNS-PEG itself shows a photothermal treatment ability under the near infrared light and this treatment can additionally promote better cellular uptake of POBNS-PEG and DOX. More importantly, POBNS-PEG was found to be able to reduce CO 2 in cancer cells to CO through photocatalytic pathways under red light irradiation for the first time. The generated CO could obviously reduce the inflammation caused by photothermal treatment and drug resistance of tumor cells caused by chemotherapy. These three combined functions bring the three-in-one multifunctional bismuthene nanosheets not only have a significant antitumor effect but also reduce the side effects, making it with high clinical potentials.

Nowadays, the two-dimensional (2D) materials have shown broad prospects for their fascinating attributes, yet the ineluctable material defects still restrict their applications. Herein, a spin-coating technology is employed to establish few-layers borophene/bismuthene/Ti 3 C 2 T x MXene/black phosphorus (BP) laminations, and then a photoelectrochemical-electrostatic coupling sensor is developed. It is demonstrated that the rough defects on the Si/Ag substrate can be patched by the upper few-layers borophene and bismuthene, and the residual defects on the Ti 3 C 2 T x layer can be exactly patched by the as-derived TiO 2 and the upper 2D BP layers. These 2D metals have been bounded with adjacent 2D semiconductors through van der Waals interactions to greatly depress the metal-induced gap states and enhance the carrier transport. Under just light irradiation or ambient electric field (AEF), the current response of the lamination electrode obviously increases, compared to that without the key BP cover layer. Further, the response can be promoted to 236.4 μA cm −2 , stimulated by AEF combined with light irradiation, which is about 1.8 times and 19.4 times higher than that of light irradiation alone and AEF alone, respectively. These can be attributed to the defect engineering effect, by which the 2D materials constantly mending the defects.

Optoelectronic science and 2D nanomaterial technologies are currently at the forefront of multidisciplinary research and have numerous applications in electronics and photonics. The unique energy and optically induced interfacial electron transfer in these nanomaterials, enabled by their relative band alignment characteristics, can provide important therapeutic modalities for healthcare. Given that nano-heterostructures can facilitate photoinduced electron–hole separation and enhance generation of reactive oxygen species (ROS), 2D nano-heterostructure-based photosensitizers can provide a major advancement in photodynamic therapy (PDT), to overcome the current limitations in hypoxic tumor microenvironments. Herein, a bismuthene/bismuth oxide (Bi/BiOx)-based lateral nano-heterostructure synthesized using a regioselective oxidation process is introduced, which, upon irradiation at 660 nm, effectively generates 1 O 2 under normoxia but produces cytotoxic •OH and H 2 under hypoxia, which synergistically enhances PDT. Furthermore, this Bi/BiOx nano-heterostructure is biocompatible and biodegradable, and, with the surface molecular engineering used here, it improves tumor tissue penetration and increases cellular uptake during in vitro and in vivo experiments, yielding excellent oxygen-independent tumor ablation with 660 nm irradiation, when compared with traditional PDT agents.

To explore the attractive structural and semiconductive properties of two-dimensional bismuthene, exquisite heterojunctions with less interfacial mismatch between bismuthene and SnO2 nanoparticle are coincidentally architected by a low-temperature procedure, based on a unique self-adaptive attribute of the two-dimensional structure of bismuthene, in combination with the lattice-matching attribute of adjacent lattice-spacing between bismuthene and SnO2. When applied in perovskite solar cells as an electron transport layer, the bismuthene–SnO2 composite layer turns smoother and more transparent and endows higher crystallinity to the upper perovskite layer. Depending on highly conductive bismuthene along with semiconductive bismuthene–SnO2 heterojunctions, the energy band of the integral composite layer is upshifted and the interfacial resistance between the composite layer and the perovskite layer is reduced, effectively accelerating the electron extraction without declining the hole-blocking, in comparison with the pure SnO2 layer. A higher statistical average power conversion efficiency of 18.75% is achieved, compared to the counterpart of 17.35%, and it also maintains a high stability of almost 80% of its initial efficiency even in an ∼5% relative humidity environment for more than 800 h, in contrast to its counterpart, which maintains just 50% efficiency retention.
