MXenes: The Emergence
Development of new materials for energy has provided hope and solutions to energy-related problems. It has also spawned many new industries and new storage systems. Electrochemical performance and safety are key factors in the composition of batteries materials. Current electrode materials are low in conductivity and surface activity. Direct contact with electrolyte can cause the material to react violently and dissolve in it. This will result, among other things, in poor structure and electrochemical stability that severely affects the material’s performance. Novoselov et al. Two-dimensional graphene microsheets exfoliated from graphite. Graphene exhibits excellent electrical conductivity, thermal conductivity as well as super high strengths, large specific surfaces, the quantum Hall effect at room temperatures, and ferromagnetism. The graphene has excellent electrochemical properties and potential applications in the area of new energy battery development. Although graphene’s excellent performance has drawn much attention, two-dimensional materials are limited in their application due to its high production cost and difficulties. It is important to search for graphene-like materials in two dimensions that have better performance than graphene. They are easy to procure and safe.
Two-dimensional material refers to crystal materials having a thickness that is only one or few atoms. One of these two-dimensional materials is graphene. Its unique electrical, magnet, mechanical and thermal properties has made it a hotspot for research. The discovery of MXenes-a two-dimensional new material has brought many more members into the two-dimensional family. Transition metal carbide and nitride called MXenes are prepared by selectively cutting the A layer of the MAX phases using a chemical liquidphase method. The structure of MXenes is very similar to graphene. Its general formula is Mn+1XnTz, where M is the transition metal element and X is either carbon or nitrogen. Tz is for functional groups like OH, O F, n=1,2,3. From the structure and performance point of view, MXene is a kind of “conductive hydrophilic clay”, Its unique advantages such as high electrical conductivity/thermal conductivity/specific surface area and good mechanical properties give MXene materials unique advantages in the electrochemical field. MXene has attracted much interest because of its exceptional structure and performance.
V2AlC Prepares MXenes
HTML2AlC, a member the MAX phase is used principally in the production MXenes via etching. A method exists to mix the fluoride and hydrochloric acids uniformly. After this, the suspension is placed in a temperature-controlled environment and stirred for about 30 seconds. Then, the suspended solution is dried under vacuum at a temperature of approximately 100°C for two-dimensional vanadium carbonide MXene powder. Two-dimensional vanadium carbonide can be prepared using this technique. This avoids the need to use high-corrosive and toxic hydrofluoric Acid.
MXenes Has Broad Application Prospects
Because of its unique structure and properties, two-dimensional material plays an important part in energy storage, conversion, catalysis and separation. MXenes may be utilized in other fields as well. V2AlC etching MXenes has good quality. V2AlC also makes a great MAX phase materials.
