Single-walled carbon nanohorn

Nanocarbons other than CNTs and graphene often exhibit similar surface chemistry and can be hybridized in a similar fashion. For example, single-walled carbon nanohorns (SWCNHs) have been oxidized via heat treatment in air atmosphere followed by immersion in a solution containing H2PtCl6. The Pt ions adsorbed to the oxidized SWCNHs and were then reduced via addition of sodium citrate to form Pt NPs [150],...

Separation of adsorption isotherms of N2 in internal and interstitial nanopores of single-walled carbon nanohorn - A comparative study with experiment and simulation... 

N2 adsorption isotherms in internal and ineterstitial nanopores of single wall carbon nanohorn (SWNH) were calculated by GCMC simulation and is compared with experimental one. Fitting of the GCMC-simulated isotherm to experimental one in internal nanopores gave the average pore width w = 2.9 nm. The N2 adsorption isotherm in the interstitial nanopores of the bundled SWNH particles well coincided with the observed one.
