| Carbon Nanospheres (CNS) that have been developed by Headwaters Technology Innovation Group (HTIG) are graphitized porous spheric structures with inner diameter controlled at 20 to 50 nm. They can be synthesized as hollow spheres or filled with metal particles in the center using a “core-shell” templating synthesis, where the uniformity and narrow particle size of the catalyzing NxCatTM iron particle core, ensure the reproducibility and unique properties of the final product. The surface and structure properties of the carbon nanospheres were investigated by SEM, TEM, Raman Spectroscopy, TGA, BET surface area, pore size and volume measurements, and XPS. Carbon nanospheres have been developed to replace or compliment existing carbon nanomaterials such as carbon nanotubes or carbon black. They can be used as: polymer & plastics filler, catalyst support; electrodes in batteries and fuel cells, filters (air, liquids), hydrogen storage, drug delivery, and more. |
