Title: Tailoring of Single Walled Carbon Nanohorns for Hydrogen Storage and Catalyst Supports

Abstract

We report the post-processing chemical treatments of single walled carbon nanohorns (SWNHs) as a medium with tunable porosity to optimize hydrogen adsorption. Laser synthesized SWNHs are oxidized in air to achieve surface areas up to 1900 m2/g. Chemistry methods are described for the decoration of SWNHs with 1-3 nm Pt nanoparticles to probe spillover and metal-assisted hydrogen storage mechanisms. Hydrogen storage of opened SWNHs is 2.6 wt% at 77K, which is 3 times as that of as-prepared SWNHs.
