Bielefeld, Germany 10.3762/bjnano.7.197 Abstract Highly uniform samples of carbonnanofoam from hydrothermal sucrose carbonization were studied by helium ion microscopy (HIM), X-ray photoelectron spectroscopy (XPS), and Raman spectroscopy. Foams with different densities were produced by changing the
and a stronger sp3-type electronic contribution, related to the inclusion of sp3 connections in their surface network.

Nanofoams are of considerable current interest due to their unique structure
sponges [17]. Carbon nanofoams have first been produced using pulsed laser ablation of glassy carbon in argon atmosphere [18] and later, as graphite in liquid nitrogen [19]. Pulsed-laser deposition has also been used for the fabrication of carbonnanofoam electrodes [20]. Carbon nanotube foam in the form
