MXenes: The Emergence
Development of new materials for energy has provided energy solutions and a new way to solve environmental issues. It has also spawned many new industries and new storage systems. Electrochemical performance, safety and future development of batteries are all affected by the composition of their electrode materials. Current electrode materials are low in conductivity and surface activity. Direct contact with electrolyte can cause material destruction, poor structure and electrochemical stability and material damage. These factors adversely affect electrode material performance. Novoselov et al. Two-dimensional graphene microsheets exfoliated from graphite. Graphene exhibits excellent electrical conductivity and thermal conductivity. It offers excellent electrochemical performances and has great potential for new energy battery applications. 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’s important to find graphene-like materials that are cheaper, easier to produce, safer, and more reliable. This is an emerging type of negative electrode material and has become a major research area.
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 hot topic 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. It has the general formula Mn+1XnTz, where M is a transitional metal element and X is 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
V2AlC, a member the MAX phase is currently being used for the manufacture of MXenes by etching. A method exists to mix the fluoride and hydrochloric alike uniformly. Next, add V2AlC powder and stir the mixture. Place the solution in a controlled temperature environment for about 30 seconds and wait for it to react. Two-dimensional vanadium carbonide can be prepared using this technique. This avoids the need to use strong corrosive or highly 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, adsorption, separation. MXenes may be utilized in other fields as well. V2AlC etching MXenes gives good results, making them a highly promising MAX Phase material.
