Titanium facilitates hydrogen dissociation at the surface of sodium alanate, an extensively studied hydrogen‐storage material, and diffusion of hydrogen into the bulk, according to hydrogen‐isotope scrambling experiments on Ti‐doped NaAlH 4 (see picture). Kinetics studies indicate that the rate‐limiting step of the charging/discharging process appears to be mass transfer into the solid.
