Evidence of Diamond Nanowires Formed inside Carbon Nanotubes from Diamantane Dicarboxylic Acid

Abstract

Carbon is a girl′s best friend: Carbon-based nanowires have been produced during thermal annealing of diamantane-4,9-dicarboxylic acid in carbon nanotubes under hydrogen atmosphere (see scheme). HR-TEM images, Raman spectra, and structural transformations observed under an intense electron beam suggest that the as-produced carbon-based nanowires are sp3 diamond nanowires, consistent with our computational results.
