Abstract

In this paper, the effect of alkaline environment on the etching of Ti₃C₂T_x-MXene was investigated and its morphology, structure and electrochemical properties were characterized. The results show that the conductivity of the Ti₃C₂T_x-MXene Solution obtained by aqueous washing reached 4.40 μS/cm, which was the highest relative to that of the Ti₃C₂T_x-MXene Solution obtained by adding NaOH, NH₃·H₂O and NaHCO₃ alkaline substances. However, the addition of excess NH₃·H₂O as well as NaOH introduces hydroxyl functional groups thereby affecting the electrical conductivity of Ti₃C₂T_x-MXene.
