Sulphur based thermochemical cycles: Development and assessment of key components of the process

Sophia Haussener, Aldo Steinfeld

HycycleS was a cooperation of nine European partners and further non-European partners and aimed at the qualification and enhancement of materials and components for key steps of solar and nuclear powered thermochemical cycles for hydrogen generation from ...

Cu-based p-type Oxide Photocathodes for Solar Hydrogen Production

Adriana Paracchino

The actualization of a hydrogen economy requires cost-effective and environmentally benign solutions to hydrogen production. Chemical energy in the form of hydrogen is more interesting than electricity to satisfy our ever-increasing energy demand because i ...

Amorphous Molybdenum Sulfide Films as Hydrogen Evolution Catalysts in Water

Daniel Andreas Merki

Molecular hydrogen is a promising candidate to replace fossil fuels as the energy carrier. Hydrogen does not exist in its molecular form on earth and must therefore be generated, starting from hydrogen-rich compounds. Water would be a renewable resource fo ...

Nanostructured alpha-Fe2O3 Photoanodes

Kevin Sivula

Due to its abundance, stability, and ability to absorb solar irradiation, Hematite, α-Fe2O3, has been investigated for its application in solar hydrogen production via water splitting for more than three decades. However, the recent application of nanostru ...

Hydrogen evolution catalyzed by MoS3 and MoS2 particles

Xile Hu, Heron Vrubel, Daniel Andreas Merki

Amorphous MoS3 particles are prepared using a simple chemical method. Several deposition techniques are developed to fabricate electrodes loaded with MoS3 particles. These electrodes are highly active for hydrogen evolution. The catalytically active specie ...

Hydrogen sensors based on palladium micro- and nanostructures for fuel cell applications

Thomas Kiefer

Hydrogen (H2) has raised considerable interest as a future energy carrier in its application to fuel cell driven vehicles, as it is absolutely free of polluting emissions. However, it is flammable in air and difficult to contain, for which reason innovativ ...

Pulse plating of Ni-W alloys from model electrolytes

Dieter Landolt

Pulse plating of nickel-tungsten alloys has been studied from two citrate ammonia based model electrolytes containing either an excess of nickel or an excess of tungsten. The alloy composition and current efficiency were determined for pulse periods rangin ...
