一种利用超声辅助制备分层的Mxene-Ti3C2的方法
摘要：
本发明涉及一种利用超声辅助制备分层的Mxene‑Ti3C2的方法，包括如下步骤：1)将Ti3AlC2‑MAX相陶瓷粉末和HF溶液混合，随后加入二甲基亚砜，得到混合液；2)将混合液进行超声处理，超声完成后，接着在油浴条件下搅拌反应；所述超声处理与搅拌反应交替重复进行，反应结束后得到中间溶液；3)将中间溶液采用去离子水进行洗涤离心，直到上清液的pH＝5～6；继续用乙醇进行洗涤离心得到沉淀物，之后干燥处理，得到分层的Mxene‑Ti3C2。该方法能够同时实现Mxene‑Ti3C2的制备及分层。
摘要（英）：

The invention relates to an ultrasound-assistant preparation method of layered Mxene-Ti3C2. The method comprises the following steps: (1) Ti3AlC2-MAX phase ceramic powder and an HF solution are mixed, and then dimethyl sulfoxide is added in order to obtain mixed liquor; (2) ultrasonic treatment of the mixed liquor is carried out, and after ultrasonic treatment is completed, a stirring reaction is carried out in an oil bath condition; ultrasonic treatment and the stirring reaction are alternatively and repeatedly carried out, and after the reaction ends, a middle solution is obtained; (3) washing and centrifugation of the middle solution are carried out by using deionized water till pH of supernatant is equal to 5-6; ethanol is used continuously in order to carry out washing and centrifugation, a sediment is obtained, drying treatment is carried out, and layered Mxene-Ti3C2 is obtained. Preparation and layering of Mxene-Ti3C2 are realized simultaneously.
