Oxygen Evolution Reaction: A New Pathway on Iridium Dioxide

Innovate and React41 minEnglish

Why watch it?

Why is the oxygen evolution reaction the bottleneck of water electrolysis, and what can theoretical chemistry do about it? Mohammad Usama, a doctoral researcher at the University of Duisburg-Essen, discusses his work on a Walden-type reaction pathway on iridium dioxide surfaces and what it could mean for catalyst design. The conversation also covers the shift from DFT to machine learning, data-driven approaches to nitrogen oxidation and automated laboratories. For electrocatalysis researchers; the related paper appeared in Nature Communications (2025).
