Title: Chemistry and Electrochemistry of 2D Carbides and Nitrides (MXenes)

2D carbides and nitrides, known as MXenes, are among the most recent, but quickly expanding material families . The field is experiencing very fast growth with the number of papers on MXenes doubling every year. Major breakthroughs have been achieved in the past 2-3 years, including the discovery of 2D M5C4 carbides with the twinned layers and CVD synthesis of MoSi2N4, representing a new family of 2D nitrides. Synthesis of dozens of predicted MXenes, demonstration of superconductivity in MXenes with specific surface terminations, stronger interactions with electromagnetic waves compared to metals, metallic conductivity combined with hydrophilicity and redox activity, led to exploration of numerous applications. Reversible redox activity of transition metal atoms in the outer layers of MXene flakes combined with high electronic conductivity led to applications in a variety of batteries and electrochemical capacitors. MXenes are promising candidates for energy storage and related electrochemical applications, such as electrocatalysis, but applications in optoelectronics, plasmonics, electromagnetic interference shielding, medicine, sensors, catalysis and water desalination are equally exciting.
