Redox chemistry and metal–insulator transitions intertwined in a nano-porous material

Berend Smit

Metal-organic frameworks are nano-porous adsorbents of relevance to gas separation and catalysis, and separation of oxygen from air is essential to diverse industrial applications. The ferrous salt of 2,5-dihydroxy-terephthalic acid, a metal-organic framew ...

Methane storage capabilities of diamond analogues

Berend Smit

Methane can be an alternative fuel for vehicular usage provided that new porous materials are developed for its efficient adsorption-based storage. Herein, we search for materials for this application within the family of diamond analogues. We used density ...

Hydrogen Sorption in Li12C60

Philippe Mauron

The lithium-intercalated fulleride Li12C60 was investigated in view of a lightweight hydrogen storage material due to the low molecular weight of its constituents. Deuterium (D2) absorption in Li12C60 shows an uptake of up to 9.5 mass % D2 (equivalent to ∼ ...
