| Abstract Scope |
Developing new nanomaterials opens the door for signifcnat technological development. In this presentation we will report on introducing a new family of two-dimensional (2D) transition metal carbo-chalcogenides (TMCCs). TMCCs can be considered as a merge between two well-known families: MXenes and transition metal dichalcogenides (TMDCs), at the atomic level. 2D Nb2S2C and Ta2S2C are the first members of TMCCs and they were delaminated from their parent multilayered structures via electrochemical lithiation followed by liquid exfoliation in water. Electronic and magnetic properties of Nb2S2C multilayers were studied, a superconductivity transition is observed at 7.55 K. When tested as electrodes for Li-ion batteries, the delaminated Nb2S2C surpasses both multilayered Nb2S2C and delaminated NbS2 in terms of capacity and stability. In addition, Ab initio calculations predicted elastic constant of TMCC to be 50% higher than that of TMDCs. |
