The Origin of the Catalytic Activity of a Metal Hydride in CO2 Reduction

Corsin Battaglia, Laetitia Bernard, Andreas Züttel, Shunsuke Kato

Atomic hydrogen on the surface of a metal with high hydrogen solubility is of particular interest for the hydrogenation of carbon dioxide. In a mixture of hydrogen and carbon dioxide, methane was markedly formed on the metal hydride ZrCoHx in the course of ...

The Environmental Photochemistry of Oxide Surfaces and the Nature of Frozen Salt Solutions: A New in Situ XPS Approach

Shunsuke Kato

Recent years have witnessed fast advancements in near ambient pressure X-ray photoelectron (NAPP) spectroscopy, which is emerging as a powerful tool for the investigation of surfaces in presence of vapors and liquids. In this paper we present a new chamber ...

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 ...
