Interlayer coupling strength dichotomizes two-dimensional (2D) materials into layered and non-layered types. Traditionally, they can be regarded as atomic layers intrinsically linked via van der Waals (vdW) forces or covalent bonds, oriented orthogonally to their growth plane. In our work, we report an unprecedented material system that differentiates from layered and non-layered materials, termed quasi-layered domino-structured (QLDS) materials. Considering the skewed structure, the force orthogonal to the 2D QLDS-GaTe growth plane constitutes a synergistic blend of vdW forces and covalent bonds, with neither of them being perpendicular to the 2D growth plane. This feature endows remarkable anisotropy, second harmonic generation enhancement with a staggering susceptibility of 394.3 pm V−1, and outstanding hydrogen evolution reaction catalytic activity with an ultra-low overpotential of 41 mV at 10 mA cm−2 and a modest Tafel slope of 73 mV dec−1. These findings endow further applications arranged in nonlinear optics, sensors, and catalysis.

MBenes can be understood as a novel family of two-dimensional metal borides which are sandwich-like structures analogues to MXenes, fabricated from encrusted MAB phases that have attracted enormous interest in the area of physical science with more emphasis on nanomaterials. These materials due to exhibiting various fascinating characteristics are claimed to have a promising future, specifically in the field of energy storage and electrocatalytic applications. Other applications explored so far include biotechnological applications. However, MBenes have not been broadly explored, and the research available on these materials is inadequate. Moreover, various other probable characteristics and uses are waiting to be explored. The current review is based on a clear understanding of MBenes, followed by their most appropriate and technical classification. Progress on the synthetic procedures, characteristics, and applications of MBenes for energy storage applications and electrocatalysis has also been explored. Subsequent discussions on current issues associated with experimental synthesis and hypothetical calculations along with perceptions and predictions about MBenes are provided.

“…A comparative study of the HER activity of Mo 2 B, α‐MoB, β‐MoB, and MoB 2 demonstrated that MoB 2 and β‐MoB exhibits excellent activity whereas the molybdenum‐rich Mo 2 B shows significantly lower activity. [ 19 , 49 ] But in another report, the CVD‐grown Mo‐rich ultrathin Mo 3 B films of 6.48 nm thickness on Mo foils exhibited fantastic stability and a lower Tafel slope of 52 mVdec −1 . [ 5 ] Theoretical studies showed the metallic nature and the faster electron transport along the active edges of the thin films helped to achieve better catalytic properties.…”

Metal borides have received a lot of attention recently as a potentially useful material for a wide range of applications. In particular, molybdenum‐based borides and MBenes are of great significance, due to their remarkable properties like good electronic conductivity, considerable stability, high surface area, and environmental harmlessness. Therefore, in this article, the progress made in molybdenum‐based borides and MBenes in recent years is reviewed. The first step in understanding these materials is to begin with an overview of their structural and electronic properties. Then synthetic technologies for the production of molybdenum borides, such as high‐temperature/pressure methods, physical vapor deposition (PVD), chemical vapor deposition (CVD), element reaction route, molten salt‐assisted, and selective etching methods are surveyed. Then, the critical performance of these materials in numerous applications like energy storage, catalysis, biosensors, biomedical devices, surface‐enhanced Raman spectroscopy (SERS), and tribology and lubrication are summarized. The review concludes with an analysis of the current progress of these materials and provides perspectives for future research. Overall, this review will offer an insightful reference for the understanding molybdenum‐based borides and their development in the future.
