Beschreibung

Allgemeine Beschreibung

Reaction kinetics of sodium aluminum hydrides may be improved by mechanical grinding or chemical modification. This may result in achieving reversible hydrogen storage at lower temperatures (80-140^oC). It may behave as a reducing agent. Reaction kinetics of graphite and Ti-doped NaAlH₄ was investigated. Presence of Ti doping enhances the kinetics of absorption and desorption. TiO₂, CeO₂, La₂O₃, Pr₂O₃, Nd₂O₃, Sm₂O₃, Eu₂O₃ and Gd₂O₃ metal oxides were studied for their catalytic behavior in improving the storage kinetics of NAlH₄.

Anwendung

NaAlH₄ may be used in the deoxygenative dimerization of carbonyls and alcohols and in hydroalumination of alkenes and alkynes.
