Abstract

original image

The electrochemically induced extraction of metal atoms from the ternary layered carbides Ti3AlC2, Ti2AlC, and Ti3SiC2 (MAX phases) at room temperature results in predominantly amorphous carbon with a narrow distribution of micropores, as described by Y. Gogotsi et al. in their Communication on page 4877 ff. This approach forgoes energy-intensive thermal processing and presents a novel method for the synthesis of carbon materials that may be used as supercapacitors, battery electrodes, or for CO2 capture.
