Descrizione

Descrizione generale

Calcium borohydride may be prepared using several techniques:

• by reacting diborane with calcium hydride/alkoxides
• by ball milling CaCl₂ and NaBH₄, resulting in an exchange reaction
• by exchange reaction between CaCl₂ and NaBH₄ in THF

Ca(BH₄)₂ decomposes partially at 360^oC and completely at 500^oC.Ca(BH₄)₂ finds use in fuel cell, a study reports the lowering of hydrogen release temperature and pressure, by using TiCl₃ as dopant.

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.

Applicazioni

Metal Borohydrides as Hydrogen Storage Materials

Calcium borohydride is a complex alkali earth metal borohydride, which has high gravimetric and volumetric hydrogen densities. It has a theoretical hydrogen capacity of 11.6 wt% and a low-reaction enthalpy of 32 kJ/mol H₂. It can be used for greener applications, which include reversible hydrogen storage.
