| 英文摘要 | 2D transition metal carbide/nitride have demonstrated wide application potential in energy storage and composites. In this article, a kind of 2D sheet structures of Ti3C2Tx MXenes were prepared through ball milling pretreatment, followed by mild etching with HCl and LiF. After ball grinding, the size of Ti3AlC2 was uniform and D-50 decreases from 4.488 mu m to 1.454 mu m which is conducive to the preparation of MXenes Ti3C2Tx with a well-defined 2D sheet structure. The microstructure of the Ti(3)C(2)T(x )was analyzed by X-ray diffraction (XRD) and scanning electron microscopy. Results of XRD showed that the (002) peak of Ti-3 AlC2 broadened and shifted from 2 theta = 9.82 degrees to 2 theta = 6.63 degrees. The corresponding interlayer distance was increased from 8.99 angstrom to 13.32 angstrom. The Ti3C2Tx MXenes phase were uniform and showed a "Tyndall effect". Obvious "accordion-like" structures were formed in Ti3C2Tx MXenes, which could achieve the etching effect of the hydrofluoric acid method. The thermogravimetric results showed that Ti3C2Tx MXenes phase prepared by this method absorbed many functional groups on the surface and had a high weight loss rate of 38.2%. All results demonstrated that the obtained Ti3C2Tx MXenes by HCl and LiF etchant via ball milling pretreatment has not only a well-defined 2D sheet structure, but also good dispersion stability and thermal stability. This article provides a new idea for the preparation of Ti3C2Tx MXenes phase. |
