Borophene has been proposed to be an energetic and promising material for electronic, optical, and thermal domains, but these applications have not been still achieved due to the metallic feature and unstable structure. The core–shell structure is a promising candidate to promote borophene for extensive applications because of fabulous multifunctional properties benefitting from the combination of diverse core and shell materials. As a favorite inner core material, Fe3O4 nanoparticles are investigated to enhance the electronic property of the core–shell particles owing to their unique semimetallic nature. Therefore, the combination of borophene and Fe3O4 nanoparticles is expected to develop high-performance electronic and sensing devices. Here, we demonstrate that borophene-functionalized Fe3O4 nanoparticles in large quantities can be prepared by heating the mixture of hydrothermally synthesized and uniform Fe3O4 nanoparticles and sodium borohydride powders under the hydrogen atmosphere as a protective gas. The structure of the shell χ4-borophene with 10 atoms per unit has been verified by combining the first-principles calculations and experimental measurements. Furthermore, a nonvolatile rewritable memory device based on the core–shell nanostructures is fabricated, and the device shows an ultrahigh on/off current ratio of 8.23 × 105 and an ultralow reset operating voltage of around 0.19 V as well as good stability.

Reduced graphene oxide (RGO) nanosheets normally possess large specific surface area, good electrical conductivity , and low density, but their unsatisfactory intrinsic complex permittivity and poor impedance matching severely hinder the further application in microwave adsorption. In this work, borophene nanosheets (BNS), the lightest 2D material , are proposed as an efficient activator to improve the microwave absorbing performance on RGO. BNS are assembled and immobilized on RGO surface through the interfacial covalent interaction, to construct a new metal-free 2D hybrid absorbent. These incorporated BNS serves as the joining site and channel in the framework to facilitate electrons hopping and migration between RGO layers . As a result, conductive loss mechanism is well enhanced, which is the major contribution to its dielectric property , conferring high impedance matching on the absorbent. As expected, the as-obtained 2D metal-free hybrid demonstrates microwave absorbing parameters that approach those of the most active absorbents, with the minimum reflection loss reaching −53.3 dB and the broadest effective absorption bandwidth of 6.16 GHz, at a low filler loading of 3 wt%.

The emergence of borophene has triggered soaring interest in the investigation of its superior structural anisotropy, a novel photoelectronic property for diverse potential applications. However, the structural instability and need of a metal substrate for depositing borophene restrict its large-scale applications toward high-performance electronic and optoelectric devices. van der Waals epitaxy is regarded as an efficient technique for growing superb two-dimensional materials onto extensive functional substrates, but the preparation of stable and controllable borophene on nonmetallic substrates is still not reported. Here, we demonstrate that borophene films can be synthesized onto a mica substrate by van der Waals epitaxy, where hydrogen and NaBH4 are respectively used as the carrier gas and the boron source. The lattice structure of the as-synthesized borophene coincides with the predicted α′-boron sheet. The borophene-based photodetector shows an excellent photoresponsivity of 1.04 A W–1 and a specific detectivity of 1.27 × 1011 Jones at a reversed bias of 4 V under illumination of a 625 nm light-emitting diode, which are remarkably superior to those of reported boron nanosheets. This work facilitates further studies of borophene toward its attractive properties and applications in novel optoelectronic devices and integrated circuits.

Borophene has attracted extensive interests owing to its distinct structural, electronic and optical properties for promising potential applications. However, the structural instability and need of metal substrate for deposition of borophene seriously restrict the exploration of its exceptional physical and chemical properties and further hamper its extensive applications towards high-performance electronic and optoelectronic devices. Here, we reported the synthesis of high-quality freestanding α-rhombohedral borophene nanosheets by a facile probe ultrasonic approach in different organic solvents. The results show that the nanosheets have high-quality in ethanol solution and have an average lateral size of 0.54 μm and a thickness of around 1.2 nm. Photoluminescence spectra indicate that a strong quantum confinement effect occurs in the nanosheets, which caused the increase of the band gap from 1.80 eV for boron powders and 2.52 eV for the nanosheets s. A nonvolatile memory device based on the nanosheets mixed with polyvinylpyrrolidone was fabricated, which exhibited a good rewriteable nonvolatile memory behavior and good stability.

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.

To gain high performance in electrochemical device , exquisite accelerating ion-electron transfer is an effective way. Here, a topological idea is realized to design a micro-leave electrode by patterning borophene-bismuthene derivative. The inner bismuthene offers high conductive skeleton, intermediate BiOCl and Bi 2 O 3 derivative as ornament contribute to supercapacitive property, and the outer borophene layer not only boosts supercapacitive property, but also reserves the topological shape. Assisted by a hydrogel electrolyte on a flexible indium-doped tin oxide substrate, a robust pressure sensor is fabricated, in which a piezoionic transfer effect is demonstrated to induce fast ions extraction and migration kinetics among the topological micro-leaves. Then the specific capacitance of electrode increases by 2.483 times comparing with the micro-leaves without borophene. The resultant robust electronic skin sensor presents a comparable sensitivity of 1.60 kPa −1 in the tiny pressure range of ≈ 50–150 Pa, and sensitivity of 1.01 kPa −1 in 150 Pa-8.5 kPa, low detection limit as 0.59 Pa, fast response/recovery time (80/80 ms), wide detection range (∼220 kPa) and reliable capacitance retention of 97.92% even after 10000 cycles. This has been successfully used to monitor the physiological signals and illustrates potential application prospects in human-computer interaction.

Borophene has emerged as a type of two-dimensional monoelemental nanomaterials with excellent drug loading capacity and photothermal properties. Here, we demonstrated the adsorption of plasma proteins onto borophene nanosheets (B NSs) and the promoted immune responses of macrophage by the B NS–corona complex. We discovered that plasma proteins changed the surface identities of B NSs. Using proteomics analysis, 46.5% of the proteins bound to B NSs (94 plasma proteins) were immune-relevant proteins. Uptake of B NSs by phagolysosomes was observed, and the plasma corona promoted the uptake. In comparison with graphene and phosphorene, we found that 32 plasma proteins appeared on all of the three nanosheets. The proportion of immune-relevant proteins in graphene–corona and phosphorene–corona was 41.3% and 75.6%, respectively. The components of the adsorbed immune-relevant proteins show diversity, which influence the immune responses of these nanosheets. Phosphorene–corona showed the most remarkable immunoregulatory behavior in these nanosheets. For the first time, we compared the highly complex protein corona at the nanosheet–plasma interface of three key 2D monoelemental nanosheets. Our study helps to understand the interaction between borophene and biological systems and provides a theoretical basis for the development and application of borophene in the biomedical field.

The ongoing pursuit of mixed-dimensional van der Waals heterojunctions has attracted enormous interests owing to their obviously enhanced photoelectrochemical (PEC) characteristics compared to their single components. Herein, we demonstrate the preparation of 0D Bismuth nanoparticles (Bi NPs) coated 2D Borophene (B@Bi) mixed-dimensional heterojunction by hydrothermal method. Benefiting from the promoted photo-induced electron/hole pair separation, shorted charge transfer length, and built-in electric field, the fabricated B@Bi-based PEC-type photodetector (PD) exhibits enhanced self-powered photodetection properties along with the fast response and recovery speed (0.02/0.02 s) in 0.5 M KOH electrolyte under 365 nm illumination. Additionally, repeatable ON/OFF switch signals can be observed after 30 days. Our present work provides an opportunity for fabricating high-performance mixed-dimensional B@Bi-based PDs with good long-term stability.
