Carbon honeycomb is a new carbon structure, which the researchers describe as three-dimensional graphene. It could store large amounts of hydrogen gas, what could benefit hydrogen economy.
Carbon can form diamond, nanotubes, or the nanoscale spheres called fullerenes, as well as several other structures. Now a team of Nina V. Krainyukova and Evgeniy N. Zubarev of Ukraine’s National Academy of Sciences and National Technical University, both in Kharkiv, Ukraine, has produced what they call carbon honeycomb, a structure that appears to have a huge gas-storage capacity. By slightly altering a common fabrication method, the researchers created what appears to be a 3D honeycomb built from the carbon sheets known as graphene.
