Abstract

Recently, a novel family of two-dimensional materials, called MXenes, comprising of early transition metal nitrides and carbides was discovered with intriguing characteristics and potential applications. MXenes are synthesized by adopting various top down and bottom up approaches such as selective etching of “A” element from MAX phases result in a new MXene element, for instance, Ti3C2, V2C, Ti3CN, MoC2, Ta4C3 etc. MXenes exhibit high metallic conductivity in which solid layers are bonded together with strong ionic, covalent and metallic bonds. The hydrophilic nature of MXene enhance its practical applications such as electrocatalyst, energy storage devices and in biomedical applications. Here, the chapter reviews the basic structure of newly discovered MXene materials, different synthesis techniques, structural, electrical and optical properties. Some potential applications in the field of biomedical, energy conversion and electrochemical energy storage systems and electrocatalyst are also presented in this chapter.
