Mechanism of Cobalt-Manganese Catalysts Deciphered

Combination of different methods was the key to success

22-Oct-2024 - The energy carrier hydrogen can be obtained from water by electrolysis. This works particularly well with Cobalt spinel electrocatalysts containing manganese. However, it was unclear why. Conventional catalysts for hydrogen production via water electrolysis usually contain precious metals and are ...

New Insights into Ammonia Decomposition

How to make hydrogen transportable

10-Oct-2024 - Using ammonia is regarded as a promising method of transporting hydrogen. However, an efficient process is also needed to convert it back into hydrogen and nitrogen. An international research team has gained new insights into the mode of operation of an iron catalyst that can be used to split ...

Making PEM electrolysis cost-efficient and scalable

Carbon-based bipolar plates have the potential to replace titanium bipolar plates in the electrolysis stack

05-Aug-2024 - Proton exchange membrane electrolysis is considered the most promising way to produce green hydrogen. However, it is still not very economical at the moment. One reason: One of its key components – the bipolar plate – is usually made of titanium. The metal impresses with its corrosion resistance ...

Maximizing Hydrogen Peroxide Formation during Water Electrolysis

Killing two birds with one stone

23-Jul-2024 - When water is split electrolytically, the result is typically hydrogen – and useless oxygen. Instead of oxygen, you can also produce a useful product. If you know how. Due to its high availability, water is considered the most useful starting material for hydrogen production. Ideally, the ...

Sustainable raw materials for a green chemical industry

Launch of the BEFuel project: From exhaust gases and wastewater to e-fuels and high-quality chemicals

29-Jan-2024 - How can e-fuels and biosurfactants for industry be produced from exhaust gases and wastewater? An interdisciplinary consortium coordinated by Fraunhofer UMSICHT is addressing this question in the newly launched BEFuel project. The focus is on coupled bioelectrochemical production – i.e. the ...

Cubes outperform spheres as catalyst particles

The shape of nanoparticles is a decisive factor in their efficiency as catalysts for the production of green hydrogen

12-Jan-2023 - To date, nanoparticles as catalysts for green hydrogen have been like rowers in an eight: researchers could only measure their average performance, but couldn’t determine which one was the best. This has now changed following the development of a new method by the group led by Professor Kristina ...

Determining the activity of noble-metal-free catalyst particles

08-Oct-2019 - Noble-metal-free nanoparticles could serve as catalysts for the production of hydrogen from water. Because they are so small, their properties are difficult to determine. Chemists have developed a new method with which they can characterise individual noble-metal-free nanoparticle catalysts. The ...

Self-healing catalyst films for hydrogen production

29-May-2017 - Chemists at the Centre for Electrochemical Sciences at Ruhr-Universität Bochum have developed a catalyst with self-healing properties. Under the challenging conditions of water electrolysis for hydrogen production, the catalyst material regenerates itself, as long as the components required for ...
