Nanocarbide-derived carbon (CDC) was synthesized at room temperature by etching Nb4AlC3 and Ti3SiC2 powders in alkali and acid solutions, respectively. The obtained CDC showed similar morphologies as the one obtained by high temperature chlorination. The CDC synthesis mechanisms included removal of Nb, Al, Ti, Si and formation of amorphous carbon phase which reordered in various structures including carbon barrel, onion, ribbon, tube, and rod. The CDC obtained from Ti3SiC2 showed high nitrogen adsorption capability of 86.8 cm(3)/g (STP) (P/P-0 approximate to 1). (C) 2014 Elsevier B.V. All rights reserved.
