Borophene, a revolutionary two-dimensional (2D) material with exceptional electrical, physical, and chemical properties, holds great promise for high-performance, highly integrated information storage systems. However, its metallic nature and structural instability have significantly limited its practical applications. To address these challenges, hydrogenated borophene has emerged as an ideal alternative, offering enhanced stability and semiconducting properties. In this study, we report a novel and scalable method for synthesizing hydrogenated borophene via the in situ thermal decomposition of potassium borohydride in a substrate-free environment. This approach enables the production of borophene with outstanding crystallinity, uniformity, and continuity, representing a significant advancement in borophene fabrication techniques. Furthermore, the hydrogenated borophene-based non-volatile memory device we developed exhibits a high ON/OFF-current ratio exceeding 10 5 , a low operating voltage of 2 V, and excellent long-term cycling stability. These groundbreaking results demonstrate the immense potential of 2D borophene-based materials in next-generation high-performance information storage devices.

As an exceptional metallic Dirac material, borophene shows promise for superior mechanical and electronic properties, making it increasingly significant in electronics. Both theoretical predictions and experimental evidence underscore its potential in energy storage applications. However, due to existing limitations in synthesis techniques, the application of stacked borophene as flexible electrodes remains unexplored. This study aims to overcome these challenges by introducing an innovative in situ co-eutectic salt method for synthesizing AB-stacked hydrogenated borophene sheets. These sheets are then employed to fabricate large-scale electrodes and construct flexible electric double-layer supercapacitors based on borophene. The robust mechanical stability of stacked borophene facilitates significant improvements in interfacial characteristics and energy storage performance through rolling processes. This enhancement results in increased specific capacity, improved rate performance, and enhanced cyclic stability of thin-film electrodes. Specifically, the optimized borophene-based supercapacitor achieves a high specific areal capacitance of up to 417.3 mF/cm 2 in an organic electrolyte at a current density of 1 mA/cm 2 , which represents a twofold improvement compared to non-stacked borophene structures. Remarkably, it retains over 88.3 % of this specific areal capacitance even at a high current density of 15 mA/cm 2 , demonstrating impressive rate capability. Furthermore, after 5000 charge–discharge cycles, the capacitance retention exceeds 89.3 %. This research is expected to catalyse the application and advancement of borophene in future flexible and portable electronic devices, highlighting its potential transformative impact in energy storage technologies.

Now a day, borophene and the related materials are of significant interest in scientific domain due to their distinguished properties. Borophene has been treated as most emerging and promising material in energy, sensor, biomedical and many other applications. Borophene has been implemented in storage applications for preparation of high performance supercapacitors (SCs) due to their better flexibility, higher capacitance, and conductivity characteristics which enable them challenging for use as electrodes superior to graphene in Scs. In view of such relevance of borophene in diversified sectors, the work in the present investigation is to survey the literature to know about synthesis, stability, characteristic properties of borophene and the related materials through the possible experimental methods so as to utilize them in the production of high performance supercapacitors. The information received from the survey reveals that the synthesis of borophene from sundry crystallographic structures of boron will impart new insights of borophene for its implementation in large scales. The Raman spectrum and zeta potential method are used for structural and stability analysis of borophene and the associated materials. In particular, Polyaniline (PANI): α borophene nano network electrode is found with high specific capacity and good stability for SCs.

Heterostructure has triggered a surge of interest due to its synergistic effects between two different layers, which contributes to desirable physical properties for extensive potential applications. Structurally stable borophene is becoming a promising candidate for constructing two-dimensional (2D) heterostructures, but it is rarely prepared by suitable synthesis conditions experimentally. Here, we demonstrate that a novel heterostructure composed of hydrogenated borophene and graphene can be prepared by heating the mixture of sodium borohydride and few-layered graphene followed by stepwise and in situ thermal decomposition of sodium borohydride under high-purity hydrogen as the carrier gas. The fabricated borophene-graphene heterostructure humidity sensor shows ultrahigh sensitivity, fast response, and long-time stability. The sensitivity of the fabricated borophene-based sensor is near 700 times higher than that of pristine graphene one at the relative humidity of 85% RH. The sensitivity of the sensor is highest among all the reported chemiresistive sensors based on 2D materials. Besides, the performance of the borophene-graphene flexible sensor maintains good stability after bending, which shows that the borophene-based heterostructures can be applied in wearable electronics. The observed high performance can be ascribed to the well-established charge transfer mechanism upon H 2 O molecule adsorption. This study further promotes the fundamental studies of interfacial effects and interactions between boron-based 2D heterostructures and chemical species.

Two-dimensional (2D) borophene has attracted tremendous interest due to its fascinating properties, which have potential applications in catalysts, energy storage devices, and high-speed transistors. In the past few years, borophene was theoretically predicted as an ideal electrode material for lithium–sulfur (Li–S) batteries because of its low-density, metallic conductivity, high Li-ion surface mobility, and strong interface bonding energy to polysulfide. But until now, borophene-based Li–S batteries have not yet been achieved in experiments due to the absence of a large-scale synthetic method of freestanding borophene nanostructures with a high enough structural stability, conductivity, and uniformity. Herein, we developed a low-temperature liquid exfoliation (LTLE) method to synthesize freestanding few-layer β12-borophene single-crystalline sheets with a symmetry in tens of milligrams. The as-synthesized 2D sheets were used as the polysulfide immobilizers and electrocatalysts of Li–S batteries. The resulting borophene-based Li–S battery delivered an extralarge areal capacity of 5.2 mAh cm–2 at a high sulfur loading of 7.8 mg cm–2, an excellent rate performance of 8 C (@721 mAh g–1), and an ultralow capacity fading rate of 0.039% in 1000 cycles, outperforming commercial Li-ion batteries and many other 2D material-based Li–S batteries. Based on the density functional theory model, the excellent electrochemical performances of the borophene-based Li–S batteries should originate from the enormous enhancement of β12-borophene sheets for both the surface migration of the Li-ions and the adsorption energy of Li2Sn clusters. Our results thus demonstrate a great potential for scalable production of freestanding β12-borophene single-crystalline sheets in future high-performance Li–S batteries.

Borophene has drawn tremendous attention in the past decade for a wide range of potential applications owing to its unique structural, optical, and electronic properties. However, applications of borophene toward next-generation nanodevices are mostly theoretical predictions, while experimental realization is still lacking due to rapid oxidation of intrinsic borophene in an air environment. Here, we have successfully prepared structurally stable and transferrable few-layer β12-borophane on copper foils by a typical two-zone chemical vapor deposition method, where bis(triphenylphosphine)copper tetrahydroborate was used as the boron source in a hydrogen-rich atmosphere to stabilize its structure through hydrogenation. The crystal structure of the as-prepared β12-borophane is in good agreement with previous reports. A fabricated photodetector based on β12-borophane–silicon (n-type) Schottky junction shows good photoelectric responses to light excitations in a wide wavelength range from 365 to 850 nm. Especially, the photodetector exhibits a good photoresponsivity of around 0.48 A W–1, a high specific detectivity of 4.39 × 1011 jones, a high external quantum efficiency of 162%, and short response and recovery times of 115 and 121 ms under an ultraviolet light with the wavelength of 365 nm at a reverse bias of 5 V. The results show great potential applications of borophane in next-generation nanophotonic and nanoelectronic devices.

Precise and real-time monitoring of the humidity value is of great significance to the living comfort and also to many applications in the field of agriculture, food and medicine. Although humidity sensors have become one of the most widely used chemical sensors, the low sensitivity and long response or recovery time have been hindering the development of this field. Due to the synergistic effect, the selection of heterostructures as sensing layer has been proven to be a simple and effective method for the next generation of high-performance humidity sensors among the proposed solutions to improve sensing performances. Here, we have successfully prepared borophene-BC2N heterostructures by in situ self-assembly under ultrasonic irradiation and fabricated the corresponding high-performance humidity sensor via a facile method. The sensor exhibits a wide detection range (11%-97%), ultra-high sensitivity (up to 22 001% at 97% RH), low hysteresis, good repeatability and fast response (11.82 s)/recovery (1.41 s). Compared to pristine borophene or BC2N QDs, borophene-BC2N heterostructures show a 100 or 20 times higher sensitivity at 97% RH at room temperature, which is the highest sensitivity among all the typical humidity sensors in previous studies. In addition, the sensor also exhibts long-term stability, excellent flexibility and high selectivity. Because of the excellent sensing performances, the heterostructured sensor can be successfully used in diaper monitoring of infants and critically ill patients, wireless monitoring of respiratory behavior and speech recognition by detecting humidity in exhalation, and non-contact switch by detecting the humidity value of the fingertip surface. This work can provide effective strategies for developing smart diapers, auxiliary voice systems, human health monitoring and prevention, and promote the development of non-contact man-machine interface systems without infectious risks.

In-situ integration of multiple materials with well-defined interfaces as heterostructures is of great interest due to their unique properties and potential for new device functionality. Because of its polymorphism and diverse bonding geometries, borophene is a promising candidate for two-dimensional heterostructures, but suitable synthesis conditions have limited its potential applications. Toward this end, we demonstrate the vertical borophene and graphene heterostructures which form by epitaxial growth of borophene onto multilayer graphene on Cu substrates via chemical vapor deposition, where hydrogen and NaBH 4 are respectively used as the carrier gas and the boron source. The lattice structure of the as-synthesized borophene well coincides with the predicted α′-boron sheet. The borophene-based photodetector shows an excellent broadband photoresponse from the ultraviolet (255 nm) to the infrared (940 nm) wavelengths, with enhanced responsivity compared to pristine borophene or graphene photodetectors. This work informs emerging efforts to integrate borophene into nanoelectronic applications for both fundamental investigations and technological applications.

As a novel approach to pursue high-performance multifunctional materials, the structural design of cutting-edge two-dimensional (2D) materials has ignited substantial interests. Borophene, an emerging member in the realm of 2D materials, exhibits crucial attributes, including high theoretical carrier density, electrical conductivity, magnetism, and high aspect ratio, rendering it highly promising for diverse applications. Yet, the exploration of porous structural configurations of borophene remains untapped. Addressing this gap, our study focuses on the fabrication of a multifunctional borophene hybrid foam (CMB-foam). This hybridization leverages the exceptional multifunctionality of MXene alongside borophene within a three-dimensional porous framework, facilitating reflection and absorption of electromagnetic waves, thereby demonstrating remarkable electromagnetic interference (EMI) shielding capabilities. Moreover, this structural configuration exposes an enlarged surface area, thus shortening the transport pathway for electrolyte ions, leading to an excellent energy storage performance. Additionally, CMB-foam performs well in thermal management and thermal insulation. These findings underscore the potential of borophene-based materials in multifunctional applications and offer valuable insights into further performance explorations in this domain.

Flexible and wearable electronic sensing devices play an increasingly important role in human health monitoring and non-contact sensors towards human to machine interface technologies. Humidity sensors have been proven to be effective in real-time respiratory monitoring and diagnostic analysis. The p–n junction of borophene–MoS2 has been theoretically predicted to have an ultrahigh humidity sensing characteristic, but the experiment is still not reported. Herein, we demonstrated experimentally a borophene–MoS2 heterostructured sensor with ultrahigh sensitivity, fast response, long life, good flexibility and high selectivity. Its sensitivity at a relative humidity (RH) of 97% is as high as 15 500%, which is more than 90 or 70 times higher than that of borophene or MoS2 alone. The sensitivity is the highest among all the reported chemiresistive sensors based on 2D materials. The corresponding swift response and recovery times are much lower than those of borophene or MoS2 alone. Additionally, the sensor shows superior flexibility under bending strain. Compared with other organic vapors, the sensor for water vapor exhibits outstanding selectivity. Besides, we also demonstrate the multifunctional applications of the sensor in human breath diagnosis and non-contact switch sensing systems, which indicates the potential of borophene-based sensors in future health care and human–machine interaction systems.

The facile synthesis of large size borophene is highly desirable, especially in reserving green energy by borophene-based Li-ion batteries (LIBs). In this study, an easy method of synthesizing a series of nickel foam (NF) deposited with borophene sheets without the use of catalysts is reported via an improved chemical vapor deposition (CVD) process. During the CVD process, the B2O2 vapor was moved to the heated nickel foam and converted into Ni3B and crystalline B under an H2 atmosphere. Numerous micron-sized lamellar borophene with thicknesses of less than 2 nm were deposited on the surface of the nickel foam, and the borophene sheets displayed ultrathin and transparency. Deep microstructural analysis revealed the crystalline nature of pure B in the as-obtained borophene sheets, and the β12-phase is dominant. The β12-borophene holds great potential for designing high-capacity anode material for LIBs. When the nickel foam-supported borophene sheets were directly used as a self-supporting binder-free anode material for LIBs, the NF framework not only hindered the aggregation of borophene sheets and alleviated the strain change during the lithiation/delithiation process but also provided a three-dimensional highway conductive network for fast electron transport. The fabricated electrodes exhibit superior lithium storage capacity and cyclic stability than blank NF electrodes. However, the results suggest that this is still far lower than the theoretical lithium storage capacity of the boron anode. The kinetics analysis combined with density functional theory calculations demonstrated that slow electron and ion transportation in the electrodes is attributed to the existence of the Ni3B phase and deactivated borophene. This study may provide vital guidance for designing high-performance borophene-based LIBs.

Poor transport kinetics, structural degradation, and an unstable electrode-electrolyte interface are the primary issues that significantly deteriorate the electrochemical performance of zinc-ion supercapacitors (ZISCs). To address these issues, we propose the concept of a hydroxylated borophene-bonded transport network embedded within a polyvinyl alcohol (PVA)/ZnSO 4 gel electrolyte (PVA/B) to construct a robust gel electrolyte. To elucidate the mechanism of this rationally designed gel electrolyte in regulating ion transport and interphase chemistry, comprehensive investigations, including simulations and diverse characterization techniques, were conducted. The results demonstrate that the formation of a C-O-B covalent bond network between the hydroxylated borophene modifier and PVA polymer facilitates rapid and uniform ion and electron transport. Moreover, the covalent bond, combined with a rough and porous surface, enhances interfacial transport kinetics. The use of the PVA/B gel electrolyte results in stable adsorption/desorption behavior and increased electric double-layer capacitance (EDLC). Additionally, gel and solid-state MXene//PVA/B//MXene ZISCs exhibit superior rate performance and cycling stability (20000 cycles). This approach provides valuable insights into gel electrolyte design and advances the development of high-performance quasi-solid ZISCs.
