ABSTRACT

The 2D layered materials named as MXenes came into the spotlight around 2011 after the synthesis of Ti3C2 by HF etching process on Ti3AlC2. The structure with the thickness of a few atoms attracted the scientific community due to its applicable electrochemical properties, high inherent conductivity, and surface area. However, the challenges of low chemical stability under high scan rates required further studies to make these 2D layered materials scalable. This chapter describes in detail the methods and strategies developed to tackle these drawbacks. First, a discussion on the importance of interlayer spacing and various strategies used to tune it is covered. Second, different approaches to change MXene’s morphology to improve electrochemical and mechanical properties are provided. Third, a combination of MXenes with other 2D materials to use for energy applications is covered in detail. The implementation of MXenes into flexible devices is covered. In summary, this chapter provides an updated discussion regarding the main concepts, synthesis, and explanation of the results to provide a clear vision for scientists to explore the properties of MXene in the energy area.
