Tellurium-Terminated MXene Synthesis via One-Step Tellurium Etching

Abstract

A novel and efficient Te etching method for the preparation of Te-functionalized MXene materials is presented This simple etching method enables the processing of V- and Nb-based MAX phases and demonstrates potential for large-scale production. V2CTex MXene has a sodium storage capacity of up to 247 mAh g−1 and maintains 216 mAh g−1 at 23 C.
