There are many grain boundaries and defects in polycrystalline perovskite films, resulting in sacrificed efficiency and instability for perovskite solar cells (PSCs). By regulating the growth of perovskite grains along the vertical direction through epitaxial growth, one may expect fewer grain-boundaries, effective charge transport, improved crystalline quality, and reduced defect density. However, there is still no suitable epitaxial growth substrate for perovskite. Here, we developed an electrochemical lithiation intercalation and ultrasonication method to prepare high-quality antimonene nanosheets (ANs). It is found that the perovskite film grows preferentially along the (012) planes of the ANs that have perfect lattice match with the (001) planes of the perovskite, leading to a high-quality perovskite film with a preferential orientation along the [001] direction and greatly enlarged grain size. Consequently, the oriented perovskite-based PSC achieves a remarkable PCE of 24.54% and shows an enhanced stability under ambient conditions, thermal annealing or light illumination. This work opens an effective avenue to effectively control the oriented growth of perovskite film for high-performance perovskite optoelectrical devices.

Advanced secondary energy storage technologies and key components are crucial to the efficient use of energy resources. Layered antimonene can facilitate ions transport and intercalation. However, the electrochemical mechanism of antimonene is very much a gray area. Herein, we show that the electrolyte ions can make appreciable differences in the energy storage behavior of antimonene. Accordingly, a high value of 599 F g −1 can be obtained by scanning antimonene electrode in 1 M H 2 SO 4 at a rate of 5 mV s −1 , which is more than twice the capacitance of those KOH, LiOH and LiCl based electrolyte systems. Systematic investigation including kinetics simulation and extrapolation of surface charge suggests a mixture of surface-controlled and battery-like Faradaic responses of antimonene in acid electrolyte. Electrochemical quartz crystal microbalance (EQCM) combined with first-principles calculation further reveals that hydrated H + is expected to access the “inner” surface sites of antimonene and thus insert or intercalate into the antimonene nanosheets. Notably, an asymmetric supercapacitor composed of antimonene positrode and carbon nanotube negatrode exhibits a wide operating voltage of 1.8 V, a relatively high energy density of 46 Wh Kg −1 at a power density of 450 W Kg −1 and great cycling performance (capacitance retention of up to 112.7% after 5000 cycles, 1.5 A g −1 ). The paper offers fundamental insights into the influence of electrolyte ions on the electrochemical behavior of 2D Xenes and pushes back the frontiers of designing energy storage systems.

Solar-thermal conversion is an efficient and convenient method that utilizes solar energy and has attracted significant attention. In this study, efficient TEMPO-oxidized nanocellulose/antimonene (TOCNF/Sb) photothermal composite films were successfully fabricated using a TOCNF layer-by-layer self-assembly strategy during vacuum-assisted filtration. TOCNF substantially improved the mechanical properties of the few-layer antimonene nanosheet film, yielding an excellent tensile strength of 302.89 MPa and toughness of 18.27 MJ/m 3 . The temperature of the TOCNF/Sb composite films reached 80.3 °C under 1 sun irradiation, and the maximum temperature was achieved within 80 s. Owing to the photothermal properties of the TOCNF/Sb composites film, the solar thermoelectric generator with the TOCNF/Sb composite film could generate a voltage of 86 mV under outdoor solar irradiation, demonstrating the feasibility in the field of solar power generation.

Peptides have higher information density than DNA and equivalent molecular recognition ability and durability. However, there are currently no reports on the comprehensive use of peptides’ recognition ability and structural diversity for sensing, logic computing, information coding, and protection. Herein, we, for the first time, demonstrate peptide-based sensing, logic computing, and information security on the antimonene platform. The molecular recognition capability and structural diversity (amino acid sequence) of peptides (Pb2+-binding peptide DHHTQQHD as a model) adsorbed on the antimonene universal fluorescence quenching platform were comprehensively utilized to sense targets (Pb2+) and give a response (fluorescence turn-on) and then to encode, encrypt, and hide information. Fluorescently labeled peptides used as the recognition probe and the information carrier were quenched and hidden by the large-plane two-dimensional material antimonene and specifically bound by Pb2+ as the stego key, resulting in fluorescence recovery. The above interaction and signal change can be considered as a peptide-based sensing and steganographic process to further implement quantitative detection of Pb2+, complex logic operation, information coding, encrypting, and hiding using a peptide sequence and the binary conversion of its selectivity. This research provides a basic paradigm for the construction of a molecular sensing and informatization platform and will inspire the development of biopolymer-based molecular information technology (processing, communication, control, security).

MicroRNA exhibits different levels of expression in cancer and can affect the transformation, metastasis, and carcinogenesis of the cancer cell. Herein, we developed a novel kind of electrochemical microRNA biosensor based on two-dimensional nanomaterial of antimonene nano-flakes (AMNFs) and carbon quantum dots (CQDs) which were used as substrating to cadmium ion (Cd 2+ ) for specific detection of breast cancer-relevant biomarker-microRNA-21. Compared to graphene, the first principle energetic calculation shows that the AMNFs have completely a stronger force interaction with single strand (ssRNA), due to the antimonene has a more delocalized 5 s/5p orbital. After the addition of complementary microRNA, due to the low adsorption affinity of double-stranded RNA (dsRNA) to antimonene, the hybridized target is easy to desorb from the antimonene interface, and the oxidation peak of metal ions is significantly reduced. Results showed the microRNA-21 concentration can be detected from 100 aM to 1 nM, the limit of detection as low as 21 aM toward microRNA-21, which is 3 times lower than those of the established microRNA biosensors. The unique combination of not be attempted before existing sensing material which has special adsorption properties represents an approach to the detection of breast cancer. And it provides a promising method for early diagnosis, monitoring, and staging of breast cancer.

In virtue of the high electrochemical activity and inherent flexibility, polyaniline (PANI) is an ideal electrode material for flexible supercapacitors (SCs). However, in practical applications, the inevitable agglomeration of PANI leads to low capacitance, poor rate performance, and cycling stability. Here, antimonene (Sb) nanosheets with ultrathin thickness, excellent mechanical strength, and flexibility are introduced into the carbon nanotube (CNT) framework for PANI electrodeposition via simple vacuum filtration, which enables the continuous and uniform growth of PANI. The resultant free-standing Sb/CNT/PANI electrode can thus exhibit a high specific capacitance of 578.57 F g −1 together with a high rate capability. Besides, thanks to the introduction of Sb nanosheets, the agglomeration of PANI during the electrodeposition is improved, which correspondingly alleviates the structural deterioration of PANI during repeated charge/discharge. Thus, the flexible SC assembled by Sb/CNT/PANI electrodes demonstrates both an impressive specific capacitance of 416 F g −1 and outstanding cycling stability over 12 000 cycles. Moreover, this SC device can have a practical self-healing function by employing self-healable polyurethane. The facile strategy reported herein sheds light on the design of high-performance flexible SCs, catering to the needs of portable and wearable electronics.

As a post graphene low dimensional material developed in the last two years, antimonene has attracted much attention. In contrast to graphite based low dimensional materials, antimonene is a bandgap semiconductor material, similar to black phosphorus, but its higher stability facilitates practical applications. Till to date, extensive theoretical studies have been conducted to explore their unique properties, but there are only a few experimental studies on their properties, let alone their applications. Therefore, in this study, high-quality antimonene oxide based low dimensional materials are prepared using a liquid exfoliation method in butanol . It is found that the antimonene oxide quantum dots have proper energy level alignment with CH 3 NH 3 PbI 3 . Consequently, they are successfully applied for perovskite solar cells based on copper doped nicklus oxide hole transfer layer, providing improved power conversion efficiency from 15.7% to near 18%. Detailed investigation shows that the performance improvement arises from enhanced charge extraction between hole transfer layer and perovskite. This study surely paves the way for the application of antimonene oxide based low dimensional materials in photovoltaic devices .

To simulate life's emergent functions, mining the multiple sensing capabilities of nanosystems, and digitizing networks of transduction signals and molecular interactions, is an ongoing endeavor. Here, multifunctional antimonene-silver nanocomposites (AM-Ag NCs) are synthesized facilely and fused for molecular sensing and digitization applications (including ultra-multi-mode and multi-analyte sensing, parallel and batch logic computing, long-text information protection). By mixing surfactant, AM, Ag + and Sodium borohydride (NaBH 4 ) at room temperature for 5 min, the resulting NCs are comprised of Ag nanoparticles scattered within AM nanosheets and protected by the surfactant. Interestingly, AM-Ag NCs exhibit ultra-multi-mode sensing ability for multiplex metal ions (Hg 2+ , Fe 3+ , or Al 3+ ), which significantly improved selectivity (≈2 times) and sensitivity (≈400 times) when analyzing the combined channels. Moreover, multiple sensing capabilities of AM-Ag NCs enable diverse batch and parallel molecular logic computations (including advanced cascaded logic circuits). Ultra-multi-mode selective patterns of AM-Ag NCs to 18 kinds of metal ions can be converted into a series of binary strings by setting the thresholds, and realized high-density, long-text information protection for the first time. This study provides new ideas and paradigms for the preparation and multi-purpose application of 2D nanocomposites, but also offers new directions for the fusion of molecular sensing and informatization.

Antimonene (Sb), a novel 2D crystalline, has recently received intense attention from optoelectronic communities, due to its enticing physical and chemical properties. Here we systematically investigate the broadband third-order nonlinear optical properties and carrier dynamics in antimonene. Efficient saturable absorption effect was observed at different wavelengths, indicating the use for broadband ultrafast laser generation. The nonlinear refractive indexes were characterized to be (2.55 ± 0.23) × 10 −14 cm 2 /W and (7.88 ± 0.37) × 10 −15 cm 2 /W at 800 nm and 1500 nm, respectively. Photoinduced carrier dynamics are investigated by a non-degenerate transient absorption spectrometer. Fast recovery processes were observed in antimonene and suggesting a high optical modulation speed to 500 GHz.

Antimonene (AMNFs) is a new kind of sp 2 -bonded honeycomb lattice two-dimensional material with strong rod-rail coupling, stability and hydrophilicity. Compared with graphene, antimonene has better sensitivity in DNA molecular sensing. We developed a suitable biosensor-Cd 2+ [email protected] @ZIF-67 nanocomposite for HER2 biomarker detection. Two-dimensional antimonene can be grown on the surface of ZIF-67 to enhance stability and biocompatibility. The aptamer chain can also be adsorbed on the surface of antimonene, and the complexes of the aptamer and the marker can be detached analytically after targeting the biomarker. The detection limit (LOD) was 4.853 fg/mL within 60 min, the detection range was 0–1000 pg/mL, and the LOD was lower than the existing HER2 aptamer biosensors. The results show that the biosensor has certain applicability and potential, and is expected to be a powerful tool for breast cancer diagnosis in the future.

In this work, soluble two-dimensional (2D) material of antimonene quantum sheets (AMQSs) is used to form a bilayer hole extraction layer (HEL) with CuSCN. It proves that the application of AMQSs helps to passivate surface defects of CuSCN, resulting in diminished recombination loss and depressed exciton quenching effect, and thereby achieving improved photovoltaic performance. In OPVs based on poly[4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)benzo[1,2-b;4,5-b']dithiophene-2,6-diyl-alt-(4-(2-ethylhexyl)-3-fluorothieno[3,4-b]thiophene-)-2-carboxylate-2-6-diyl)]: [6,6]-phenyl C71-butyric acid methyl ester (PTB7-Th:PC71BM), over 12% enhancement of power conversion efficiency (PCE) is observed compared to that of the reference cell fabricated with pure CuSCN as an HEL. The advantage of the bilayer CuSCN/AMQS HEL is also confirmed in non-fullerene systems of PBDB-T-2F:IT-4F and PTB7-Th:ITIC. In a cell based on PBDB-T-2F:IT-4F, a PCE of 10.14% was obtained after application of AMQSs, which improved by about 10% compared to that of the reference cell using pure CuSCN as an HEL. Furthermore, cells based on CuSCN and CuSCN/AMQS HEL exhibit superior air stability. The use of a bilayer CuSCN/AMQS HEL provides a promising approach to obtain efficient and stable organic solar cells.

Improved efficiency and stability of the organic solar cells (OSCs) are the critical considerations for practical applications. The interface between the interlayer and bulk heterojunction has recently been shown as one of the weak links associated with the degradation in the nonfullerene acceptor (NFA)-based OSCs. It shows that the removal of the interfacial chemical reactions between the 2-(3-oxo-2,3-dihydroinden-1-ylidene)malononitrile (INCN) moieties in NFA and poly(3,4-ethylenedioxythiophene)-polystyrene sulfonate (PEDOT:PSS) hole extraction layer (HEL) is desired for enhancing the device stability. In this work, we show that the use of a bilayer MoO 3 /antimonene HEL favors the operational stability in OSCs through maintaining a high built-in potential and suppression of an undesired interfacial reaction between INCN moieties in NFA and the PEDOT structures in PEDOT:PSS. A power conversion efficiency of 16.68% is also obtained for the OSCs with a bilayer MoO 3 /antimonene HEL, prepared using a blend system of PM6:Y6, demonstrating its suitability for high-performance OSCs.
