Two-dimensional (2D) metal-boride-derived nanostructures have been a focus of intense research for the past decade, with an emphasis on new synthetic approaches, as well exploration possible applications in next-generation advanced materials and devices. Their unusual mechanical, electronic, optical, chemical properties, arising from low dimensionality, present paradigm to science metal borides that has traditionally focused their bulk properties. This Perspective discusses current state 2D...
Abstract Layered metal diborides that contain atoms sandwiched between boron honeycomb planes offer a rich opportunity to access graphenic forms of boron. We recently demonstrated magnesium diboride (MgB 2 ) could be exfoliated by ultrasonication in water yield boron‐based nanosheets. However, knowledge the fate boride crystals aqueous phases is still its incipient stages. This work presents our preliminary findings on discovery MgB can undergo dissolution under ambient conditions result...
Ultrasonication within organic solvents is widely used to exfoliate layered materials and produce two-dimensional (2D) nanostructures. Several 2D synthesized by such liquid-phase exfoliation (LPE) approaches are reported exhibit photoluminescence. In these approaches, it presumed that while the nanostructures derived from parent material undergoing delamination, solvent serves as a dispersing medium. However, in this study, we show also contributes toward formation of optically active. We...
Metal boride nanostructures have shown significant promise for hydrogen storage applications. However, the synthesis of nanoscale metal particles is challenging because their high surface energy, strong inter- and intraplanar bonding, difficult-to-control termination. Here, it demonstrated that mechanochemical exfoliation magnesium diboride in zirconia produces 3-4 nm ultrathin MgB2 nanosheets (multilayers) yield. High-pressure hydrogenation these multilayers at 70 MPa 330 °C followed by...
Layered boron compounds have attracted significant interest in applications from energy storage to electronic materials device applications, owing part a diversity of surface properties tied specific arrangements atoms. Here we report the landscape for atomic configurations MgB2 by combining first-principles calculations, global optimization, material synthesis and characterization. We demonstrate that contrary previous assumptions, multiple disordered reconstructions are thermodynamically...
Metal borides have attracted the attention of researchers due to their useful physical properties and unique ability form high hydrogen-capacity metal borohydrides. We demonstrate improved hydrogen storage a nanoscale Mg–B material made by surfactant ball milling MgB2 in mixture heptane, oleic acid, oleylamine. Transmission electron microscopy data show that nanoplatelets are produced with sizes ranging from 5 50 nm, which agglomerate upon ethanol washing produce an agglomerated micron-sized...
