Journal ArticleDOI
Interaction of zirconia with magnesium hydride and its influence on the hydrogen storage behavior of magnesium hydride
D. Pukazhselvan,David Alexandre Reis Silva,K. S. Sandhya,Sara Fateixa,Aliaksandr L. Shaula,Helena I. S. Nogueira,Igor Bdikin,Duncan P. Fagg +7 more
TL;DR: In this paper , the authors demonstrate how a zirconia additive transforms to Zirconium hydride and substantially lowers the dehydrogenation temperature of magnesium hydroxide.
