A new way to make iridium catalysts for hydrogen production last longer
Researchers have developed a new high-entropy perovskite material to stabilize iridium catalysts used in water electrolysis. This innovation aims to increase the durability of catalysts, making hydrogen production more efficient and cost-effective.
Why it matters
Improving catalyst longevity is essential for scaling green hydrogen production, a key component in the transition to renewable energy systems.

Water electrolysis is a promising method that uses electricity to split water into hydrogen and oxygen without producing carbon dioxide (CO₂).
Among the different approaches to water electrolysis, proton exchange membrane (PEM) electrolysis stands out for its ability to respond quickly to changes in electricity supply. This flexibility makes it particularly well suited for use with renewable energy sources such as wind and solar power.
