Fuchi Bei Guoping, Zhongming & Shibo Li & Weiwei Zhang, Beijing Jiaotong University: Tomorrow's rising star two-dimensional carbonitride MXenes: From synthesis, performance to application

Research background

Since its discovery, two-dimensional (2D) MXenes has become a research hotspot in various fields. More than 100 members of the MXenes family have been reported so far, and they exhibit amazing and fascinating properties such as electrical conductivity, microwave absorption, optical properties, and so on. Recently, it was found that the physical and chemical properties of carbon nitride MXenes are better than those of carbides MXenes. The N atom replaces the C atom in the carbon-nitride MXenes, and because N has higher electronegativity than C, its lattice parameters and electron distribution are changed, so the properties are also changed. With further research, MXenes is expected to fill the gap between emerging technologies and new material needs, playing an important role in key areas such as communications, stealth, and energy storage.
