Functionalised metal-organic frameworks: a novel approach to stabilising single metal atoms

We have investigated the potential of metal-organic frameworks for immobilising single atoms of transition metals using a model system of Pd supported on NH2-MIL-101(Cr). Our transmission electron microscopy and in situ Raman spectroscopy results give evid ...

Stabilization of volatile Ti(BH4)(3) by nano-confinement in a metal-organic framework

Andreas Züttel, Elsa Callini

Liquid complex hydrides are a new class of hydrogen storage materials with several advantages over solid hydrides, e.g. they are flexible in shape, they are a flowing fluid and their convective properties facilitate heat transport. The physical and chemica ...

Nanostructured materials for solid-state hydrogen storage: A review of the achievement of COST Action MP1103

Andreas Züttel, Elsa Callini

In the framework of the European Cooperation in Science and Technology (COST) Action MP1103 Nanostructured Materials for Solid-State Hydrogen Storage were synthesized, characterized and modeled. This Action dealt with the state of the art of energy storage ...

Complex and liquid hydrides for energy storage

Andreas Züttel, Elsa Callini, Ping Chen

The research on complex hydrides for hydrogen storage was initiated by the discovery of Ti as a hydrogen sorption catalyst in NaAlH4 by Boris Bogdanovic in 1996. A large number of new complex hydride materials in various forms and combinations have been sy ...

Manipulating the reaction path of the CO2 hydrogenation reaction in molecular sieves

Rolf Erni, Davide Ferri, Andreas Züttel, Elsa Callini

We demonstrate that the kinetics of the Sabatier reaction catalysed by sorption catalysts depends on the nanostructure of the catalyst-sorbent system. The catalysts are prepared by ion exchange of a nickel nitrate solution in two zeolites with different po ...

The catalyzed hydrogen sorption mechanism in alkali alanates

Andreas Züttel, Shunsuke Kato, Elsa Callini, Philippe Mauron

The hydrogen sorption pathways of alkali alanates were analyzed and a mechanism for the catalytic hydrogen sorption was developed. Gibbs free energy values of selected intermediate steps were calculated based on experimentally determined thermodynamic data ...

Storing Renewable Energy in the Hydrogen Cycle

Andreas Züttel, Shunsuke Kato, Elsa Callini

An energy economy based on renewable energy requires massive energy storage, approx. half of the annual energy consumption. Therefore, the production of a synthetic energy carrier, e.g. hydrogen, is necessary. The hydrogen cycle, i.e. production of hydroge ...

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 ...
