Herein we report, a simple novel method to synthesize nanosized Ti₃AlC₂ powder from Ti, Al, and C powders in NaCl–KCl molten salt. It is more conducive to the formation of Ti₃AlC₂ at higher salt/precursor materials ratio and particle size of Ti₃AlC₂ powder dramatically decreases with increasing mass ratio of the salt to precursor materials. Fine-grained Ti₃AlC₂ powder is successfully synthesized at 950^○C for 5 h or at 1000^○C for 2 h with a salt/precursor materials ratio of 10:1. Ti₃C₂ MXene is also prepared by etching fine-grained Ti₃AlC₂ precursor in HF solution at 60°C for 2 h.

在NaCl–KCl熔融盐中合成纳米Ti ₃ AlC ₂粉末的简单方法

本文中，我们报道了一种简单的新颖方法，可以从NaCl–KCl熔融盐中的Ti，Al和C粉末合成纳米尺寸的Ti ₃ AlC ₂粉末。它更有利于在较高的盐/前体材料比下形成Ti ₃ AlC ₂，并且随着盐与前体材料的质量比增加，Ti ₃ AlC ₂粉末的粒径显着减小。细粒度的Ti ₃ ALC ₂粉末在950成功地合成^○ ℃下5小时或在1000 ^○ ℃2小时为10的盐/前体材料：1的比例。钛₃ C ₂还可以通过在60°C的HF溶液中蚀刻细颗粒的Ti ₃ AlC ₂前驱体2小时来制备MXene 。
