Abstract: Several doping substances were tested as to the effectiveness of the catalyst they yielded for the de- and hydrogenation of sodium alanate. The milling process through which the doped samples are synthesized was improved through the addition of a device to measure the hydrogen evolution in situ during milling. A single-step synthesis of doped NaAlH₄ in a high pressure mill was developed, yielding samples with improved characteristics. An automatic isobaric cycling apparatus was built and programmed, which allowed stability experiments over a long period of time, as well as the identification of hydrogenation rate maxima at two different pressures. Finally, the role of the catalyst in the hydrogen molecule splitting reaction was observed in isotope exchange experiments, as well as hydrogen exchange between the sample bulk and the gas atmosphere under mild conditions.
