The most favorable dopants for solid‐state hydrogen‐storage materials are still considered to be compounds of titanium in spite of intensive research on other catalysts. Here, we show that NaAlH 4 doped with ScCl 3 is a highly efficient dopant, both with respect to storage capacity and kinetics: 2 mol % ScCl 3 exhibits a nearly theoretical hydrogen‐storage capacity (4.9 wt %, see graph). Other rare‐earth metal trichlorides are also investigated.
