Less is more: Why an economical Iridium catalyst works so well

Different chemical environments explored

10-Dec-2024 - Iridium-based catalysts are needed to produce hydrogen using water electrolysis. Now, a team at HZB has shown that the newly developed P2X catalyst, which requires only a quarter of the Iridium, is as efficient and stable over time as the best commercial catalyst. Measurements at BESSY II have ...

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.

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 ...
