NaAlH₄ is an important hydrogen storage material with 5.6 wt% hydrogen content.

Nb₂O₅ is a promising catalyst for the hydrogen desorption from sodium alanate

Dehydrogenation of NaAlH₄ converts it to a great extent to Na₃AlH₆.

Nb₂O₅ doped NaAlH₄ desorbed 5.0 wt% hydrogen less than theoretical capacity of 5.6%.

Catalyst reduces hydrogen desorption temperature from 285 °C to 250 °C.
