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...
A novel high-purity V2C MXene two-dimensional carbide, was successfully synthesized by etching V2AlC with sodium fluoride and hydrochloric acid at 90°C for 72 h. From the analysis of X-ray diffraction, energy dispersive spectra, photoelectron spectroscopy, purity as-synthesized >90 wt% a few impurities Na5Al3F14 V2AlC. The made this method much purer than those HF room temperature. as-prepared showed excellent electrochemical properties as anode lithium-ion batteries. capacity can be 260 mAh...
The effect of etching solution on the synthesis process two-dimensional vanadium carbide (V₂C MXene) was researched. Three solutions were used to etch ternary V₂AlC at 90 °C. three were: lithium fluoride + hydrochloric acid (LiF HCl), sodium and potassium (KF HCl). It found that only NaF HCl effective for synthesizing highly pure V₂C MXene. existence (Na⁺) chloridion (Cl-) in essential synthesis. thermal stability as-prepared MXene argon or air studied. From thermogravimetry differential...
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...
Abstract Two-dimensional carbide MXenes (Ti 3 C 2 T x and V CT ) were prepared by exfoliating MAX phases AlC AlC) powders in the solution of sodium fluoride (NaF) hydrochloric acid (HCl). The specific surface area (SSA) as-prepared Ti was 21 m /g, that 9 /g. After intercalation with dimethylsulfoxide, SSA increased to 66 /g; 19 Their adsorption properties on carbon dioxide (CO investigated under 0–4 MPa at room temperature (298 K). Intercalated had capacity 5.79 mmol/g, which is close many...
Abstract Nowadays, photocatalytic technologies are regarded as promising strategies to solve energy problems, and various photocatalysts have been synthesized explored. In this paper, a novel CdS/MoO 2 @Mo C-MXene photocatalyst for H production was constructed by two-step hydrothermal method, where MoO acted binary co-catalyst. the first step, crystals with an egged shape grew on surface of two-dimensional (2D) Mo C MXene via oxidation process in HCl aqueous solution. second CdS nanorods...

Abstract The development of 2‐dimensional materials has expanded beyond the realm graphene, and now includes inorganic transition metal oxides/hydroxides, which show promise for a wide range applications. As an emerging class nanoscale materials, they unprecedented properties that are unattainable in their bulk lamellar systems, can be attributed to confined thickness compared several tens micrometer lateral dimensions. Such qualities make them viable candidates battery supercapacitor There...
MXene is a new type of two-dimensional layered material. Herein, GO/Ti3C2Tx nanocomposite was prepared by simple liquid phase method, and the obtained transformed into RGO/Ti3C2Tx under high temperature with Ar/H2. The samples were characterized using X-ray diffraction (XRD), Raman measurement, scanning electron microscopy (SEM), energy disperse spectroscopy (EDS), photoelectron (XPS).

Combining both chemical and physical cross-links in a double-network hydrogel (DN gel) has emerged as promising design strategy to obtain highly mechanically strong hydrogels. Unlike chemically cross-linked DN gels, little is known about the fracture process toughening mechanisms of hybrid physically linked gels. In this work, we engineered tough gels agar/polyacrylamide (Agar/PAAm) by combining two types polymer networks: linked, first agar network chemical-linked, second PAAm network. The...
