Activation of the reactive hydride composite 2NaBH4+MgH2

A novel method to enhance the reaction kinetics of the reactive hydride composite 2NaBH4 +MgH2 is described. It has been discovered that short-term exposure to a moist atmosphere has a very beneficial effect on the desorption reaction of the 2NaBH4 +MgH2 mixture. By this procedure it is possible to...

Summary:A novel method to enhance the reaction kinetics of the reactive hydride composite 2NaBH4 +MgH2 is described. It has been discovered that short-term exposure to a moist atmosphere has a very beneficial effect on the desorption reaction of the 2NaBH4 +MgH2 mixture. By this procedure it is possible to achieve, after drying, both faster desorption kinetics and greater amounts of released hydrogen compared to ball-milled material without further treatment.
