Abstract
Two-dimensional (2D) nanomaterials including graphene, hexagonal boron nitride (h-BN), transition metal dichalcogenides (TMDs), and MXenes have attracted much attention because they present a wide range of physicochemical, optoelectronic, and mechanical properties along with various atomic structures and compositions. MXenes represent the largest and rapidly growing family of 2D transition metal carbides and/or nitrides, which exhibit unique combinations of properties, including metallic conductivity, hydrophilic surface chemistry, redox-active surface, and plasmonic behavior that make them attractive as electrodes for pseudocapacitive energy storage to coatings for electromagnetic interference shielding, transparent conducting displays for optoelectronics, conductive yarns for functional textiles, implantable electrodes for medicine, and many other applications. MXenes are typically derived via topochemical etching of atomically thick layers from precursor layered MAX phases using corrosive aqueous etchants. However, the chemical etching process is only somewhat optimized for one composition, and is nonetheless often slow, with low-yield, and results in defects in the materials.
