Nitrogen Adsorption by Activated Carbon Saturated with Fullerenes
The ability of activated coal (AC) to capture and hold fullerenes is associated with the AC pore structure and considerably differs for different ACs. To reveal the nature of the AC holding capacity, the authors studied adsorption of nitrogen by AC samples at 77K after treatment by C60 fullerene. For measurements, an Autosorb-1 (Quantachrome Instrument Co., Florida, USA) device was employed. Variations in the pore size distribution are evidence for the role of 1.5-2.0 nm pores in the holding of fullerene C60.
