Plasma-Liquid Synthesis as a New Method for the Production of MXenes

In this work, the successful synthesis of nanostructures based on MXenes by initiating a pulse discharge between titanium wires immersed in carbon tetrachloride is presented. By choosing carbon tetrachloride as the environment, the formation of oxide structures in the synthesized samples could be avoided. The characterization of the obtained structures was carried out using various techniques, including scanning electron microscopy, X-ray phase analysis, EDS, Raman and FTIR spectroscopy. The results confirmed the successful formation of MXenes with a Cl- occupying the interlayer space. The properties of the discharge initiated in CCl4 were also determined. The results suggest the potential of this plasma-liquid method for the synthesis of high-purity MXenes without impurities commonly found in conventionally prepared samples.
