“…Benefitting from the experience of graphene, stanene can be exfoliated by liquid‐phase exfoliation, which is a powerful and promising approach for mass production. Ma et al 79 established a facile and feasible dealloying strategy to fabricate few‐layer stanene. First, a high‐temperature solid‐state reaction of Li film and Sn powder was carried out to prepare layered precursor Li 5 Sn 2 .…”

“…But, the lack of suitable electrode materials strictly hinders the development of metal-ion batteries. Graphene, a class of superior thermal and electrical conductors, can not only act as a conductive filler but also form the desirable nanocomposite electrode structures in conjunction with carbon nanotubes, transition metal oxides, and so forth to enhance ion infusion, electron transfer, and alleviate the volume [79] expansion. [80][81][82]90,[91][92][93][94][95][96] The strategy for the feasible nanostructured assembly of a three-dimensional porous graphene/ niobia (Nb 2 O 5 ) composite was applied by Sun et al 83 to prepare the 3D electrode architecture delivering high areal capacity and high-rate capability at practical levels of mass loading.…”

“…The topotactic synthesis of siloxene has also been examined as silicon‐based intercalation electrodes, which suffered from the rapid structure deterioration and capacity fading in Li, Na, and K ion batteries 89 . A facile and general dealloying method was presented to fabricate metallic buckled stanene nanosheets with favorable accommodation of K atoms 79 . The high surface areas and unprecedented electronic properties of group‐VA nanosheets enable them broad perspectives of future technologies.…”

Graphene, an emerging fabric of carbon atoms, has manifested its versatility in all kinds of fields encompassing electronics, optoelectronics, thermoelectrics, taking advantage of its excellent mechanical strength, exceptional electronic and thermal conductivities, high surface specific area, and so forth. The prosperity of graphene never seen before has led the attention to silicene, siloxene, germanene, stanene, and plumbene due to their promising applications in the quantum spin Hall effect, topological insulator, batteries, capacitors, catalysis, and topological superconductivity. Herein, we review the existing production methods, numerous applications of two‐dimensional group‐IVA materials, and critically discuss the challenges of these materials, providing potential implications to the exploration of uncharted material systems.

“…Meanwhile, this bottom-up approach to synthesize 2D Sn faces one unsolvable problem is that it is greatly difficult to transfer them from the growth substrates and use them for practical applications [ 27 ]. Although some other methods such as using ultra-fast femtosecond laser or dealloying strategy also successfully fabricate 2D SnNSs [ 28 , 29 ], the cumbersome operations, expensive costs, and the large size of obtained Sn seriously limit the further applications, especially the biological applications of 2D Sn. At present, experimental efforts to synthesize 2D Sn through chemical manipulation and use it in practical applications are still in the stage of optimization morphology, mass production, and miniaturization.…”

Stanene (Sn)-based materials have been extensively applied in industrial production and daily life, but their potential biomedical application remains largely unexplored, which is due to the absence of the appropriate and effective methods for fabricating Sn-based biomaterials. Herein, we explored a new approach combining cryogenic exfoliation and liquid-phase exfoliation to successfully manufacture two-dimensional (2D) Sn nanosheets (SnNSs). The obtained SnNSs exhibited a typical sheet-like structure with an average size of ~ 100 nm and a thickness of ~ 5.1 nm. After PEGylation, the resulting PEGylated SnNSs (SnNSs@PEG) exhibited good stability, superior biocompatibility, and excellent photothermal performance, which could serve as robust photothermal agents for multi-modal imaging (fluorescence/photoacoustic/photothermal imaging)-guided photothermal elimination of cancer. Furthermore, we also used first-principles density functional theory calculations to investigate the photothermal mechanism of SnNSs, revealing that the free electrons in upper and lower layers of SnNSs contribute to the conversion of the photo to thermal. This work not only introduces a new approach to fabricate 2D SnNSs but also establishes the SnNSs-based nanomedicines for photonic cancer theranostics. This new type of SnNSs with great potential in the field of nanomedicines may spur a wave of developing Sn-based biological materials to benefit biomedical applications.

“…A diversity of materials, such as metal alloys [13,14], selenides [5], oxides [15,16], MXene [17,18], and carbon-based material [19] have been studied as battery-type anodes. Among them, carbon-based materials [10,[20][21][22][23] with the intercalation mechanism are considered as one of the most promising anode candidates for large-scale practical applications thanks to the attractive merits of low cost and high electrical conductivity.…”

Potassium-ion hybrid capacitors (PIHCs) tactfully combining capacitor-type cathode with battery-type anode have recently attracted increasing attentions due to their advantages of decent energy density, high power density, and low cost; the mismatches of capacity and kinetics between capacitor-type cathode and battery-type anode in PIHCs yet hinder their overall performance output. Herein, based on prediction of density functional theory calculations, we find Se/N co-doped porous carbon is a promising candidate for K+ storage and thus develop a simple and universal self-sacrifice template method to fabricate Se and N co-doped three-dimensional (3D) macroporous carbon (Se/N-3DMpC), which features favorable properties of connective hierarchical pores, expanded interlayer structure, and rich activity site for boosting pseudocapacitive activity and kinetics toward K+ storage anode and enhancing capacitance performance for the reversible anion adsorption/desorption cathode. As expected, the as-assembled PIHCs full cell with a working voltage as high as 4.0 V delivers a high energy density of 186 Wh kg−1 and a power output of 8100 W kg−1 as well as excellent long service life. The proof-of-concept PIHCs with excellent performance open a new avenue for the development and application of high-performance hybrid capacitors.
