为了验证是否可以利用氢氟酸刻蚀Cr2AlC制备二维晶体MXene,本文采用气氛保护管式炉,在不同合成温度、保温时间及配比条件下制备出Cr2AlC样品,通过XRD图谱分析找出最佳原料配比为Cr∶ Al∶C =2∶ 1.1∶1,合成温度为1400℃,保温时间为1h.然后在此工艺条件下,制备疏松的样品,并用砂纸打磨去掉含有较多杂质的表层,然后把样品粉磨成大小不同的颗粒.这些颗粒放入氢氟酸中处理,将真空干燥后的反应产物进行XRD分析,结果表明Cr2AlC样品颗粒越小,反应时间越长,反应温度越高,HF酸浓度越高,Cr2AlC越容易被腐蚀,但是反应产物中均不存在二维晶体MXene,证明利用HF酸刻蚀Cr2 AlC制备二维晶体MXene的方法不可行.
