Abstract

We report the first example of nanosize-induced hydrogen storage in a metal that does not absorb hydrogen in its bulk form. Rhodium particles with diameters of <10 nm were found to exhibit hydrogen-storage capability, while bulk Rh does not absorb hydrogen. Hydrogen storage was confirmed by in situ powder X-ray diffraction, solid-state 2H NMR, and hydrogen pressure - composition isotherm measurements. The hydrogen absorption capacity could be tuned by controlling the particle size.
