ABSTRACT: Metal hydrides with high hydrogen density provide promising hydrogen storage paths for hydrogen transportation. However, the requirement of highly pure H2 for re-hydrogenation limits its wide application. Here, amorphous Al2O3 shells (10 nm) were deposited on the surface of highly active hydrogen storage material particles (MgH2-ZrTi) by atomic layer deposition to obtain MgH2-ZrTi@Al2O3, which have been demonstrated to be air stable with selective adsorption of H2 under a hydrogen atmosphere with different impurities (CH4, O2, N2, and CO2). About 4.79 wt% H2 was adsorbed by MgH2-ZrTi@10nmAl2O3 at 75 °C under 10%CH
