High surface area carbon nanotube-supported titanium carbonitride aerogels

Abstract

In this study, the synthesis and characterization of a high surface area titanium carbonitride aerogel are presented. The aerogels were made by the carbothermal reduction of a titania-coated carbon nanotube-based foam under flowing nitrogen at 1400 °C. The resulting monoliths consisted of titanium carbonitride (TiC_1−xN_x, x = 0.95) nanocrystals supported by the nanotubes and exhibited surface areas in excess of 250 m²/g.
