Layered vanadium-based MXene material and preparation method thereof
The preparation method of the lamellar vanadium-based MXene material comprises the following steps: taking a V2AlC MAX phase ceramic material and anhydrous magnesium chloride, mixing, and fully and uniformly grinding to obtain a mixture A; placing the mixture A in a tubular furnace in a vacuum or inert atmosphere, fully reacting at 700-900 DEG C, and naturally cooling to room temperature after the reaction is finished to obtain a powder product B; alternately centrifugally cleaning the product B with deionized water and ethanol to obtain a precipitate; and carrying out vacuum drying on the precipitate to obtain the lamellar vanadium-based MXene material. According to the preparation method disclosed by the invention, the two-dimensional lamellar material with a relatively large specific surface area can be obtained by controlling the size and the morphology of the vanadium-based MXene material. An anhydrous magnesium chloride melting method is adopted for etching, namely a tubular furnace high-temperature reaction in the second step, the prepared vanadium-based MXene material is of a lamellar structure, the thickness is about 10-50 nm, the nanosheet size is about 200-500 nm, the MAX surface appearance is evenly etched, the material structure is stable, and the material has a large specific surface area.
