This seems quite remarkable if true -hydrogen loading ratio 16:1 with cerium
"Insight into anomalous hydrogen adsorption" ....Shreeja Das, et al
Hydrogen interaction withmetal atoms is of prime focus for many energy related
applications... but itsbinding properties with lanthanides are not well
reported. In this article, bydensity functional theory studies, we show how a
rare earth metal, cerium,binds with hydrogen... Each cerium atom is found to
bind eight hydrogenmolecules which is a much higher number than has been
reported fortransition metal atoms.
