Abstract:<\/h4>\n
Large scale synthesis and delamination of 2D Mo 2 CT x (where T is a surface termination group) has been achieved by selectively etching gallium from the recently discovered nanolaminated, ternary transition metal carbide Mo 2 Ga 2 C. Different synthesis and delamination routes result in different flake morphologies. The resistivity of free\u2010standing Mo 2 CT x films increases by an order of magnitude as the temperature is reduced from 300 to 10 K, suggesting semiconductor\u2010like behavior of this MXene, in contrast to Ti 3 C 2 T x which exhibits metallic behavior. At 10 K, the magnetoresistance is positive. Additionally, changes in electronic transport are observed upon annealing of the films. When 2 \u03bcm thick films are tested as electrodes in supercapacitors, capacitances as high as 700 F cm \u22123 in a 1 m sulfuric acid electrolyte and high capacity retention for at least 10,000 cycles at 10 A g \u22121 are obtained. Free\u2010standing Mo 2 CT x films, with \u22488 wt% carbon nanotubes, perform well when tested as an electrode material for Li\u2010ions, especially at high rates. At 20 and 131 C cycling rates, stable reversible capacities of 250 and 76 mAh g \u22121 , respectively, are achieved for over 1000 cycles.<\/p>\n","protected":false},"excerpt":{"rendered":"
