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 ...

Water electrolysis is a cornerstone of global sustainable and renewable energy systems, facilitating the production of ...

"There is actually only one catalyst -- iridium oxide -- that remains stable." However, an increasing number of studies have reported that COFs are also long-term stable in this reaction.

In 2021, Wang synthesized an iridium single-atom (Ir-SA) heterogeneous catalyst by implementing a two-step thermal degradation. This Ir-SA catalyst was then employed to catalyze the insertion of ...

Iridium (Ir)-based materials ... By examining a highly active and porous catalyst with a singular hydroxylated Ir suboxide species, the study develops a nanosheet atomistic model that surpasses ...

“The reaction conditions in the oxygen evolution reaction are harsh,” explains Kristina Tschulik. “There is actually only one catalyst – iridium oxide – that remains stable.” However, an increasing ...

One promising approach since the late 1990’s is the use of iridium with stable terdentate “pincer” ligands as alkane dehydrogenation catalysts: Calculations suggest that pincer ligands with ...

Researchers are particularly focused right now on catalysts that use platinum and iridium oxide to create hydrogen and oxygen, respectively, since those materials are commercially available.
