Synthesis of MXene/carbon composites via controlled etching of Ti 3 SiC 2 in the gaseous etchant CCl 4
Source abstract
Abstract
The study investigates the structural evolution of Ti3SiC2 using the gaseous etchant CCl4, emphasizing its ability to selectively etch Si and Ti atoms to form an MXene (Ti3C2Cl2)/carbon composite and carbide-derived carbon (CDC). Under specific conditions, a complete conversion to the MXene is accomplished at a Ti3SiC2 : CCl4 molar ratio of 1 : 3.5, whereas higher CCl4 concentrations lead to further oxidation of Ti3C2Cl2 and formation of lamella CDC. This method presents an alternative chemical etching route to synthesize MXenes. Importantly, the production of CDC using CCl4 as an etchant could obtain carbon/MXene hybrids with significant implications for promising energy storage applications.
