[资源] AM25年纪念，MX相：一种新型的二维层状材料

Yury Gogotsi在AM上发表长篇综述，阐述了一类二维层状结构的MX材料，并且详细的介绍了MX相结构材料的制备方法和潜在的应用前景。进一步阐述了通过选择性刻蚀的方法合成一系列的MX相二维超薄片，MX二维超薄片进一步拓展了MX材料的应用前景。并且MX结构是合成一系列氮化物或者碳化物二维单层超薄片的有效的中间产物。全文14页，引文70篇！
Recently a new, large family of two-dimensional (2D) early transition metal carbides and carbonitrides, called MXenes, was discovered. MXenes are produced by selective etching of the A element from the MAX phases, which are metallically conductive, layered solids connected by strong metallic, ionic, and covalent bonds, such as Ti2AlC, Ti3AlC2, and Ta4AlC3. MXenes combine the metallic conductivity of transition metal carbides with the hydrophilic nature of their hydroxyl or oxygen terminated surfaces. In essence, they behave as “conductive clays”. This article reviews progress—both experimental and theoretical—on their synthesis, structure, properties, intercalation, delamination, and potential applications. MXenes are expected to be good candidates for a host of applications. They have already shown promising performance in electrochemical energy storage systems. A detailed outlook for future research on MXenes is also presented.
