Beryllium borohydride, with the chemical formula Be(BH4)2, is a chemical compound composed of beryllium (Be) cations and borohydride (BH4-) anions. It is a solid material that is a source of hydrogen gas (H2) when it reacts with water.

Beryllium borohydride is a highly reactive compound and is typically used as a hydrogen storage material, as it can release hydrogen gas upon hydrolysis. When beryllium borohydride is exposed to water, it undergoes a hydrolysis reaction, producing beryllium hydroxide (Be(OH)2) and hydrogen gas:

Be(BH4)2 + 4H2O -> Be(OH)2 + 2H2 + 4BH3

Hydrogen storage materials like beryllium borohydride have been studied for their potential use in hydrogen fuel cells and other hydrogen-based energy storage systems. However, they face challenges related to storage efficiency, cost, and safety.

It’s essential to handle beryllium borohydride with extreme caution due to its reactivity and potential hazards. Beryllium compounds, in general, are known to be toxic and should be handled with appropriate safety measures to avoid exposure.

As with any highly reactive or potentially hazardous compound, specialized training and safety protocols should be followed when working with beryllium borohydride to ensure the safety of researchers and lab personnel.
