Hydrogen Storage in Novel Organometallic Buckyballs
Abstract
Transition metal (TM) atoms bound to fullerenes are proposed as adsorbents for high density, room temperature, ambient pressure storage of hydrogen. ${\mathrm{C}}_{60}$ or ${\mathrm{C}}_{48}{\mathrm{B}}_{12}$ disperses TMs by charge transfer interactions to produce stable organometallic buckyballs (OBBs). A particular scandium OBB can bind as many as 11 hydrogen atoms per TM, ten of which are in the form of dihydrogen that can be adsorbed and desorbed reversibly. In this case, the calculated binding energy is about $0.3\text{ }\text{ }\mathrm{eV}/{\mathrm{H}}_{2}$, which is ideal for use on board vehicles. The theoretical maximum retrievable ${\mathrm{H}}_{2}$ storage density is $\ensuremath{\sim}9\text{ }\text{ }\mathrm{wt}\text{ }%$.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
