Partially Oxidized Ti₃C₂T_<i>x</i> MXenes for Fast and Selective Detection of Organic Vapors at Part-per-Million Concentrations

MXenes, two-dimensional transition metal carbides or nitrides, have recently shown great promise for gas sensing applications. We demonstrate that the sensitivity of intrinsically metallic Ti3C2Tx MXene can be considerably improved via its partial oxidation in air at 350 °C. The annealed films of MX... View More
