Abstract
NaBH 4 exhibits a high gravimetric storage capacity. However, rapid hydrolysis reaction already under air moisture, connected with hydrogen release (2.4 1 H 2/g in the reaction with H 2O), prevent easy technical applications (uncontrollable loss of hydrogen and risk of self ignition). Solidified NaBH 4- gel provides a new and safe way of hydrogen storage on the basis of moisture protection of boranate by an aluminosilicate composite matrix. Details of synthesis and principal hydrogen release properties of this new boranate gel will be presented in this contribution. The composite compound has a high hydrogen storage capability with maximum enclosure of up to 72 wt% of NaBH 4. Besides its simple preparation method, a controlled H 2 release on demand is possible by addition of very few amount of slightly acid diluted solution. A pH-controlled total hydrogen release up to 1.71 H 2/g is realized from the gel according to the reaction NaBH 4+2H 2O → NaBO 2+4H 2. It can be concluded that the NaBH 4-aluminosilicate gel provides a new and safe way of hydrogen storage.
