摘要：

V2AlC is a typical ternary intermetallic compound and a precursor to synthesis 2D-MXenes V2C. This work used cheap metal oxides and carbon as simple starting materials to fabricate MAX phases carbide V2AlC by molten salt electrolysis, and the obtained product could be converted into 2D V2C by a chemical etching process easily. The obtained ultrafine V2AlC possess high purity and homogeneity, and the 2D V2C from the chemical etching presented a unique layered Nano-sheets structure. TEM and X-ray photoelectron spectroscopy were combined to analysis the micromorphology and the chemical bonding states. And the reaction mechanism has been investigated to explore the facile synthetic method of V2AlC and 2D V2C.
