Ultrathin, lightweight, and flexible electromagnetic‐interference (EMI) shielding materials are urgently required to manage increasingly serious radiation pollution. 2D transition‐metal carbides (MXenes) considered promising alternatives graphene for providing excellent EMI‐shielding performance due their outstanding metallic electrical conductivity. However, the hydrophilicity of MXene films may affect stability reliability when applied in moist or wet environments. Herein, first time, an...
The functional groups and site interactions on the surfaces of two-dimensional (2D) layered titanium carbide can be tailored to attain some extraordinary physical properties. Herein a 2D alk-MXene (Ti3C2(OH/ONa)xF2–x) material, prepared by chemical exfoliation followed alkalization intercalation, exhibits preferential Pb(II) sorption behavior when competing cations (Ca(II)/Mg(II)) coexisted at high levels. Kinetic tests show that equilibrium is achieved in as short time 120 s. Attractively,...
In this study, from experiments and theoretical calculation, we reported that Ti3C2 MXene can be applied as sensors for NH3 detection at room temperature with high selectivity. MXene, a novel two-dimensional carbide, was prepared by etching off Al atoms Ti3AlC2. The as-prepared multilayer powders were delaminated to single layer intercalation ultrasonic dispersion. colloidal suspension of single-layer Ti3C2-MXene coated on the surface ceramic tubes construct gas detection. Thereafter, used...
Searching for reversible hydrogen storage materials operated under ambient conditions is a big challenge material scientists and chemists. In this work, using density functional calculations, we systematically investigated the properties of two-dimensional (2D) Ti2C phase, which representative recently synthesized MXene ( ACS Nano 2012 , 6 1322 ). As constituent element 2D Ti atoms are fastened tightly by strong Ti-C covalent bonds, thus long-standing clustering problem transition metal does...

Quantum dots, derived from two-dimensional (2D) materials, have shown promising applications in bioimaging, photocatalysis, biosensors and white light emission devices (W-LEDs).
For high capacities and extremely fast charging rates, two-dimensional (2D) crystals exhibit a significant promising application on lithium-ion batteries. With density functional calculations, this paper systematically investigated the Li storage properties of eight 2D M2CO2 (M = V, Cr, Ta, Sc, Ti, Zr, Nb, Hf), which are recently synthesized transition-metal carbides (called MXenes) with O groups. According to whether structural transformation occurs or not during adsorption first layer, can...
