Reversible hydrogen absorption in sodium intercalated fullerenes

Philippe Mauron

The hydrogen absorption of sodium intercalated fullerenes (Na xC60) was determined and compared to pure fullerenes (C60). Up to 3.5 mass% hydrogen can reversibly be absorbed in Na xC60 at 200 °C and a hydrogen pressure of 200 bar. The absorbed amount of hy ...

Phase-field simulation of micropores constrained by the dendritic network during solidification

Alain Jacot, Hossein Meidani

A phase-field model has been developed to describe the morphology of pores constrained by a dendritic solid network, and are forced to adopt complex non-spherical shapes. The distribution of the solid, liquid and gas phases was calculated with a multiphase ...

Highly active oxide photocathode for photoelectrochemical water reduction

Michael Graetzel, Kevin Sivula, Vincent Laporte, Adriana Paracchino

A clean and efficient way to overcome the limited supply of fossil fuels and the greenhouse effect is the production of hydrogen fuel from sunlight and water through the semiconductor/water junction of a photoelectrochemical cell, where energy collection a ...

Gold catalysis at the gas-solid interface: role of the support in determining activity and selectivity in the hydrogenation of m-dinitrobenzene

Fernando Cardenas Lizana

The catalytic gas phase hydrogenation of m-dinitrobenzene (1 atm, 423 K) over laboratory synthesised (1 mol%) Au supported on Al2O3, TiO2, Fe2O3 and CeO2 and a reference Au/TiO2 (World Gold Council) has been investigated. The catalysts were prepared by dep ...

A multifaceted approach to hydrogen storage

Bengt Kasemo

The widespread adoption of hydrogen as an energy carrier could bring significant benefits, but only if a number of currently intractable problems can be overcome. Not the least of these is the problem of storage, particularly when aimed at use onboard ligh ...

Hydrogen Dynamics in Lightweight Tetrahydroborates

The high hydrogen content in complex hydrides such as M[AIH 4]x and M[BH4]x (M = Li, Na, K, Mg, Ca) stimulated many research activities to utilize them as hydrogen storage materials. An understanding of the dynamical properties on the molecular level is im ...

Effect of additives on the synthesis and reversibility of Ca(BH4)(2)

Metal borohydrides are potential materials for solid-state hydrogen due to their high gravimetric and volumetric hydrogen densities. Among them, Ca(BH4)2 is particularly interesting because of the predicted suitable thermodynamic properties. In this work, ...

Pd-functionalized MEMS resonator for hydrogen gas sensing at ambient pressure

Jürgen Brugger, Luis Guillermo Villanueva Torrijo, Thomas Kiefer, Jonas Gustav Henriksson

This work presents the fabrication and characterization of a novel hydrogen-detecting micro-resonator based on the expansion of palladium (Pd) as it is exposed to hydrogen (H2) gas. The working principle of the device has been confirmed and it shows a stro ...

A quasi-Delphi study on technological barriers to the uptake of hydrogen as a fuel for transport applications : production, storage and fuel cell drivetrain considerations

François Richard Vuille

The introduction of hydrogen in transport, particularly using fuel cell vehicles, faces a number of technical and non-technical hurdles. However, their relative importance is unclear, as are the levels of concern accorded them within the expert community c ...
