Recent studies increasingly highlight the potential applications of MBenes, a novel class of two-dimensional (2D) materials, yet their production remains challenging. In this context, microcrystalline MoAlB (space group ; = 3.080(3) Å, = 11.57(1) Å, and = 3.149(4) Å), a promising precursor for MoB MBene production, was synthesized in a single-step gas-solid reaction at 450 °C using MoAlB and gaseous HCl. This preparation method, previously utilized for the oxidation of Zintl phases, has been successfully adapted to compounds containing -block elements, providing a new alternative for exfoliating layered materials in liquid solutions. Scanning electron microscopy analysis revealed homogeneous products with microcrystals exhibiting a nonuniform particle size distribution. At higher temperatures, these evolved into plate-like crystallites with smooth surfaces and etch cavities. This efficient and cost-effective gas-solid reaction shows great potential for large-scale production of a wide range of 2D materials, with significant benefits for catalysis, energy storage, and other applications.
最近的研究越来越多地强调了新型二维（2D）材料MBenes的潜在应用，但其生产仍然具有挑战性。在此背景下，微晶MoAlB（空间群；= 3.080(3) Å，= 11.57(1) Å，= 3.149(4) Å），一种用于生产MoB MBene的有前景的前驱体，在450°C下通过MoAlB与气态HCl的一步气固反应合成。这种先前用于氧化Zintl相的制备方法已成功应用于含-block元素的化合物，为在液体溶液中剥离层状材料提供了一种新的替代方法。扫描电子显微镜分析显示产物均匀，微晶呈现出不均匀的粒径分布。在较高温度下，这些微晶演变成具有光滑表面和蚀刻腔的板状微晶。这种高效且经济的气固反应在大规模生产各种二维材料方面显示出巨大潜力，对催化、储能和其他应用具有显著益处。
