US Patent 7837968 - Carbon nanosphere


Fullerenes, carbon nanotubes, and carbon nanohorns have all been suggested as electrode materials for fuel cell catalysts. This latest patent from Samsung teaches another variety of carbon nanostructure to increase the surface area for catalyst support. Claim 1 reads:

1. A carbon nanosphere having at least one opening, and having a diameter of about 100 nm to about 350 nm and a thickness of about 5 nm to about 30 nm.
