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 Mo2AlB2 (space group Cmmm; a = 3.080(3) & Aring;, b = 11.57(1) & Aring;, and c = 3.149(4) & Aring;), a promising precursor for MoB MBene production, was synthesized in a single-step gas-solid reaction at 450 degrees C using MoAlB and gaseous HCl. This preparation method, previously utilized for the oxidation of Zintl phases, has been successfully adapted to compounds containing d-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.
