Influence of Nanoconfinement on the Hydrogen Release Processes from Sodium Alanate
Kenneth Tuul,Rasmus Palm +1 more
- 18 Jan 2021
TL;DR: In this article, the impact of nanoconfinement on the H2 release processes from NaAlH4 and the limitations of each process in case of bulk and nanoconfined NaAl H4 are presented and discussed.

In situ neutron diffraction of NaAlD4/carbon black composites during decomposition/deuteration cycles and the effect of carbon on phase segregation
Rasmus Palm,Kenneth Tuul,F Elson,Elisabetta Nocerino,Ola Forslund,Thomas F. Hansen,Jaan Aruväli,Martin Mansson +7 more
TL;DR: In this paper , the influence of mesoporous carbon black on the decomposition and reforming of the hydrogen storage material NaAlH4 was investigated with in situ diffraction, and a 60:40 NaAlD6/carbon black composite was prepared via ball milling and characterised ex situ via X-ray diffraction.
