Submicron Ti3AlC2 grains are grown in molten salt. Etching the grains gives rise to small-sized Ti3C2Tx MXene particulates with capacitance more than twice that of the large ones derived from conventional high-temperature synthesis. Detailed electrochemical, structural, and spectroscopic studies demonstrate that increased capacitance predominantly originates from a decrease in the lateral size of the small Ti3C2Tx MXene particulates.
在熔融盐中生长出亚微米级的 Ti3AlC2 颗粒。对这些颗粒进行刻蚀，得到的小型 Ti3C2Tx MXene 颗粒的电容比传统高温合成得到的大型颗粒高出两倍以上。详细的电化学、结构和光谱研究表明，电容的增加主要源于小型 Ti3C2Tx MXene 颗粒横向尺寸的减小。
