Abstract: Provided are methods of effecting cation exchange in MXene materials so as to stabilize the materials. Also provided are compositions, comprising layered MXene materials that comprise an organic cation between layers. Also provided are MXene compositions comprising a chalcogen disposed thereon, the MXene composition further optionally comprising a quaternary ammonium halide disposed thereon.
