Ti3C2Tx MXene Based Nanostructured Materials for Emerging Applications

Two-dimensional (2D) transition-metal carbides, carbonitrides, and nitrides, also referred to as MXenes, have received a lot of attention since the initial discovery of Ti3C2 in 2011. Ti3C2 MXenes have become new candidates with excellent potential for use in optoelectronic devices, such as photovoltaics, photodetectors, and photoelectrochemical devices, due to their exceptional electronic, optical, mechanical, and thermal properties, versatile structures, and surface chemistries. The key to Ti3C2 MXene nanostructures’ success in a variety of electronic and photonic device applications is their excellent metallic conductivity, high anisotropic carrier mobility, good structural and chemical stabilities, high optical transmittance, excellent mechanical strength, tuneable work functions and wide range of optical absorption properties. Here, we provide an overview of the fundamental characteristics, manufacturing process, and optoelectronic applications of functionalized Ti3C2 MXenes, pure Ti3C2 MXenes, and hybrid nanocomposites. Finally, the outlook and existing difficulties of Ti3C2 MXenes towards the creation of sophisticated MXene-based nanostructures for future applications are briefly explored.
