AbstractMXene, a new family of 2D materials, possesses excellent electrical conductivity and hydrophilicity. To date, the majority of MXenes are only successfully produced by exfoliating the MAX phases with high concentration hydrofluoric acid (HF). In this study, the 2D MXene Ti3C2with larger interplanar spacing was successfully obtained by etching Ti3AlC2with bifluoride (NaHF2, KHF2, NH4HF2) in single-stage process. The morphology, structure and element composition of prepared Ti3C2samples were characterized by scanning electron smicroscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), energy dispersive spectrometer (EDS). The synthesis mechanism of Ti3C2was elaborately demonstrated. The possible reaction equations between Ti3AlC2and different bifluorides were generalized, indicating the formation of hydrosoluble by-products of Na3AlF6,K3AlF6and (NH4)3AlF6. This work presents a safely effective method to synthesize the 2D nanocrystals MXene. © 2016 Elsevier Ltd
