From Catalyst Design to Climate Impact

Can we finally move beyond iridium in acidic water electrolysis?

Green hydrogen is one of the pillars of the clean energy transition, but its scalability is still limited by costly and scarce noble-metal catalysts.

In a new published study in Small Structures, by Dr. Hannah-Noa Barad and her team they demonstrate a promising pathway toward precious-metal-free acidic OER catalysts.

By strategically incorporating transition metals (Mo and W) into LaNiO₃ and leveraging a high-throughput discovery platform, we identified compositions that deliver:

This work combines advanced materials engineering, surface chemistry, and automated electrochemical screening, accelerating the discovery process while generating deep mechanistic insight.

The implications? More affordable proton exchange membrane (PEM) electrolyzers and a realistic path toward scalable green hydrogen production.
