Dear colleagues and friends,

This Friday at 15:30 Berlin time (13:30 UTC), we will have the 30th online #theLightStuff lecture. Here, Dr. Mi Tian from the University ofExeter will talk about Hydrogen storage materials and Neutron scattering.https://www.bam.de/Content/EN/Events/2020/thelightstuff/2020-10-23-the-light-stuff-online-lectures-tian.html

Neutron ‘Sees’ Hydrogen Confined in Nanopores
Dr Mi Tian, University of Exeter, GB
Nanoporous materials can adsorb large quantities of gases owing to the increased density of the gas inside the pores. Hydrogen, in its solid-state, offers far more compact energy storage density and capacity. We employed inelastic neutron scattering (INS) to prove the formation of solid-like hydrogen confined in nanopores. We identified the optimal porous structure to achieve the immobilised hydrogen with an extremely high density at mild conditions, without which we would not achieve such high hydrogen density. Then quasielastic neutron scattering (QENS) was then used to quantitatively illustrate the immobile and partially mobile H2 confined in pores at 35 K up to 130 K, indicating the population of immobile and partially mobile H2 is temperature-dependent. This confirmation of the effects of pore geometry and pore size on the confinement of molecules is essential in understanding and guiding the development and scale-up of porous adsorbents that are tailored for maximising H2 storage capacities, in particular for sustainable energy applications.
