Facile synthesis of hollow Ti3AlC2 microrods in molten salts via Kirkendall effect
文献摘要：
The microstructure and morphology of Ti3AlC2 powders not only affect the preparation of Ti3C2 MXene but also have a great influence on their potential applications,such as microwave absorbers,alloy additives,or catalytic supports.However,the synthesis of Ti3AlC2 powders with desired microstructure and morphology remains a challenge.Herein,hollow Ti3AlC2 microrods were prepared for the first time in NaCl/KCl molten salts by using titanium,aluminum,and short carbon fibers as starting materials.It was found that the short carbon fibers not only performed as carbon source but also acted as sacrificial template.Furthermore,it was revealed that TiC and Ti2AlC were initially formed on the surface of carbon fibers.The subsequent reactions between the outer Ti,Al and the inner carbon were dominated by the Kirkendall effect which gave rise to the formation of a hollow structure.Based on this mechanism,hollow Ti3AlC2 microspheres and a series of hollow TiC,Ti2AlC,and V2A1C powders were also successfully fabricated.This work provides a facile route to synthesize hollow MAX phases and may give enlightenment on preparing other hollow carbide powders via the Kirkendall effect in the molten salts.
