The Figure illustrates methane densities adsorbed at 303 K and 3.5 MPa in pores of lanthanide-nitrate-dispersed, single-walled carbon nanohorns (SWNHs). For reference, bulk methane density and methane density adsorbed in pores of as-grown SWNH are also depicted. A small amount of lanthanide-nitrate dispersion (0.1 mmol lanthanide nitrate per gram of SWNH) has been shown to strongly enhance methane adsorption.
