Abstract

Transmission electron microscopy (TEM) has been used to characterize NaAlH4, doped with Ti, after H cycling. NaAlH4 was shown to be highly unstable under the electron beam, and "knock on" damage lead to a decomposition of NaAlH4 with Na and H evaporating from the sample. All Ti containing phases were stable under the electron beam. After H cycling, the Ti was present as a mixture of amorphous and crystalline Al1-xTix.
