Abstract
Open carbon single-wall nanotubes (SWNTs) are essentially elongated pores with diameters of molecular dimensions. Here we present evidence that SWNTs are selectively opened by oxidation with H2O resulting in CO2 production and hydrogen termination of the tube ends. Temperature programmed desorption (TPD) measurements revealed significant H2 adsorption on open 12 A diameter SWNTs at near ambienttemperatures. The data suggest that adsorbed H2 is stabilized within the internal cavities of carbon nanotubes by nanocapillary forces. Optimization of methods for producing SWNTs might allow these unique materials to be utilized for large-scale storage and purification of gases. Towards this goal, we employed both transmission electron microscopy (TEM) and H2 TPD to optimize single-wallnanotube content as a function of rod translation rate during synthesis.
