Critical raw materials from electrolysers back into the cycle

Researchers succeed in recycling functional materials for hydrogen production

13-May-2025 - Hydrogen plays a central role in the energy transition. The gas is mainly produced with the help of electrolysers. This process requires critical raw materials such as platinum group metals, rare earths or nickel as catalysts. Researchers at the Helmholtz Institute Freiberg for Resource ...

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 ...

Novel synergistic single-atom catalyst approach breaks activity limitation of predecessors

While the developed synergistic catalyst does not erase the need for noble metals, it does reduce the amount needed for a better reaction

28-Mar-2022 - The key to chemical reactions is in the name — there needs to be something that causes the chemicals to react to one another. Called a catalyst, this component induces or speeds up reactions in a controlled manner to produce a desired outcome. The catalysts used in several industries are often ...
