Electrosynthesis of Ti3AlC2-Derived Porous Carbon in Molten Salt

Tailored Electrosynthesis of Highly Porous Ti3SiC2-Derived Carbon Anodes with Excellent Lithium Storage Properties

“…Molten salt electrochemical etching (MSE) has been proved to be a promising method for the synthesis of CDCs, which shows the facile and environmentally friendly features, and the molten salt has also been proved to be beneficial for the generation of tunable mesoporous architecture. − In our recent work, SiC nanowire and its derived carbon have been successfully prepared through the facile route (SiO 2 /C → SiC → CDC) and the prepared porous carbon nanowires exhibited excellent capacitance and good stability as supercapacitors due to its unique hierarchical pore structures, which were attributed to the molten salt etching process. Subsequently, the strategy has also been extended to etch MAX (Ti 3 SiC 2 and Ti 3 AlC 2 ) for the synthesis of mesopore-rich 2D CDCs, , which shows to be promising as a general strategy for the controllable synthesis of 2D CDC with porous structures. However, the conversion process from MAX material to CDC still needs detailed investigation; in particular, the transformation from MAX to CDCs may involve complex processes such as oxidation, atomic migration, and structural evolution − and thus disclosure of detailed transformation processes is extremely needed.…”
