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.
一种片层状钒基MXene材料及其的制备方法,取V2AlC MAX相陶瓷材料和无水氯化镁,混合并充分研磨均匀得到混合物A;在真空或惰性气氛下,将混合物A置于管式炉中,在700~900℃充分反应待反应结束后自然冷却至室温,得到粉末产物B;将产物B用去离子水、乙醇交替离心清洗干净得沉淀物;将沉淀物真空干燥得到片层状钒基MXene材料。本发明的制备方法通过控制所述钒基MXene材料的尺寸和形貌可以获得具有较大的比表面积的二维片层状材料。采用无水氯化镁熔融法刻蚀即步骤2管式炉高温反应,所制备的钒基MXene材料呈现片层状结构,厚度约为10~50nm,纳米片尺寸约为200~500nm,MAX表面形貌被刻蚀均匀,材料结构稳定,具有较大比表面积。
