英文摘要	In this work, the MXene Ti3C2 with excellent electrical conductivity is obtained by etching Ti3AlC2 with NH4HF2 solution. The electrosorption performance, theelectrochemicalandphysicochemical properties of as-prepared Ti3C2 are characterized. The results demonstrate that NH4HF2-etched Ti3C2 possesses the better intercalation pseudo-capacity and the specific capacitance is up to 78F.g(-1), which is an increase of 34% than HF-etched Ti3C2. In addition, the desalination capacity of NH4HF2-etched Ti3C2 enhances 35.5% than that of HF-etched Ti3C2. When the initial conductivity of NaCl is similar to 1000S/cm, the desalination capacity of NH4HF2-etched Ti2C3 electrode is 12.1mg.g(-1), and the pseudo-first-order model can well describe the electrosorption kinetics of NH4HF2-etched Ti3C2 electrode. Furthermore, the regeneration performance of the NH4HF2-etched Ti3C2 electrode is excellent. This study indicates a new kind of effective electrode material to improve the desalination performance of capacitive deionization (CDI) technology.
