Title

Unraveling the structure of water clusters in microporous aluminophosphates AlPO4-34 and AlPO4-LTA

Abstract

Microporous aluminophosphates AlPO4-34 and AlPO4-LTA are among the most promising materials for sorption-based heat storage. They store energy in their dry state and release it during hydration. With the proposed project, we are aiming to gain insight into the mechanism of (de)hydration of these materials with neutron total-scattering experiments. In particular, we would like to obtain information about the short-/mid-range order of the hydration-induced framework deformation and about the structure of hydrogen-bonded water clusters within the pores, because they are considered decisive for energy storage performance.
