I ridium-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 ...

"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.

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 ...

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 ...

Proton-exchange membrane water electrolysers often rely on scarce iridium or ruthenium catalysts at the anode, as many low-cost, earth-abundant catalysts cannot withstand the harsh operational ...

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 ...

One of the goals is the development of low-iridium (Ir) catalysts, addressing the scarcity and high cost of iridium, a critical component in proton exchange membrane (PEM) electrolyzers.

Two different Iridium-based nanocatalysts for water electrolysis were examined by a HZB-led team: A commercial benchmark catalyst (left) and the newly developed P2X catalyst (right), which is more ...

In this joint effort, Hydrous Iridium Oxide Thin Films (HIROFs ... By examining a highly active and porous catalyst with a singular hydroxylated Ir suboxide species, the study develops a nanosheet ...
