Nowadays, two‐dimensional materials have many applications in materials science. As a novel two‐dimensional layered material, MXene possesses distinct structural, electronic, and chemical properties; thus, it has potential applications in many fields, including battery electrodes, energy storage materials, sensors, and catalysts. Up to now, more than 70 MAX phases have been reported. However, in contrast to the variety of MAX phases, the existing MXene family merely includes Ti2C, Ti3C2, (Ti1/2, Nb1/2)2C, (V1/2, Cr1/2)3C2, Nb2C, Ti3CN, Ta4C3, V2C, and Nb4C3. Among these materials, the Ti3C2Tx MXene exhibits prominently high volumetric capacitance, and the rate at which it transports electron is suitable for electrode materials in batteries and supercapacitors. Hence, Ti3C2Tx is commonly utilized as an electrode material in ion batteries such as Li+, Na+, K+, Mg2+, Ca2+, and Al3+ batteries. What is more, Ti2C has the biggest specific surface area among all of these potential MXene phases, and therefore, Ti2C has remarkably high gravimetric hydrogen storage capacities. In addition, Ti2CO2 materials display extremely high activity for CO oxidation, which makes it possible to design catalysts for CO oxidation at low temperatures. Furthermore, Ti3C2Tx with O, OH, and/or F terminations can be used for water purification owing to excellent water permeance, favorable filtration ability, and long‐time operation ability. This review supplies a relatively comprehensive summary of various applications of MXenes over the past few years.

功能性MXene材料:其应用进展

如今,二维材料在材料科学中有许多应用。作为一种新颖的二维层状材料,MXene具有独特的结构,电子和化学特性。因此,它在许多领域都有潜在的应用,包括电池电极,储能材料,传感器和催化剂。到目前为止,已经报告了超过70个MAX阶段。但是,与各种MAX相相比,现有的MXene系列仅包含Ti 2 C,Ti 3 C 2,(Ti 1/2,Nb 1/22 C,(V 1/2,Cr 1/23 C 2,Nb 2 C,Ti 3CN,Ta 4 C 3,V 2 C和Nb 4 C 3。在这些材料中,Ti 3 C 2 T x MXene具有显着的高体积电容,并且其传输电子的速率适用于电池和超级电容器中的电极材料。因此,Ti 3 C 2 T x通常用作诸如Li +,Na +,K +,Mg 2 +,Ca 2+和Al 3+电池之类的离子电池中的电极材料。而且,Ti 2C在所有这些潜在的MXene相中具有最大的比表面积,因此Ti 2 C具有非常高的重量氢存储容量。另外,Ti 2 CO 2材料显示出极高的CO氧化活性,这使得可以设计用于低温下的CO氧化的催化剂。此外,由于具有出色的透水性,良好的过滤能力和长期运行能力,带有O,OH和/或F末端的Ti 3 C 2 T x可以用于水净化。这篇综述提供了过去几年中MXene的各种应用的相对全面的摘要。
