Hydrogen Desorption Kinetics in Metal Intercalated Fullerides

For different hydrogenated metal intercalated fullerides (Na10C60-H, Li12C60-H, and Li28C60-H) the activation energies for hydrogen desorption were determined by DSC. The Vyazovkin advanced method (VA) was used for the calculation of the reaction model fre ...

Storage of Renewable Energy by Reduction of CO2 with Hydrogen

Marco Roman Holzer, Andreas Züttel, Shunsuke Kato, Elsa Callini, Philippe Mauron, Jianmei Huang

The main difference between the past energy economy during the industrialization period which was mainly based on mining of fossil fuels, e.g. coal, oil and methane and the future energy economy based on renewable energy is the requirement for storage of t ...

Surface Reactions are Crucial for Energy Storage

Andreas Züttel, Shunsuke Kato, Elsa Callini, Philippe Mauron

Reactions between gas molecules, e.g. H-2 and CO2 and solids take place at the surface. The electronic states and the local geometry of the atomic arrangement determine the energy of the adsorbate, i.e. the initial molecule and the transition state. Here w ...

Structure of the Orthorhombic gamma-Phase and Phase Transitions of Ca(BD4)(2)

Andreas Züttel, Philippe Mauron

We have solved and refined the crystal structure of the orthorhombic gamma-phase of Ca(BD4)(2) by combined synchrotron X-ray powder diffraction, neutron powder diffraction, and ab initio calculations. Among five structural candidates giving the same qualit ...
