Researchers discovered that adding nickel oxide during hydrogen-based iron ore reduction doubles reaction rates and enables reduction to begin at temperatures as low as 300°C. The transient formation of nanoporous nickel catalyzes hydrogen dissociation and spillover onto iron oxides, accelerating metal extraction while supporting a low-carbon, one-step route for producing industrial iron–nickel alloys used in stainless and high-strength steels. https://www.nature.com/articles/s44160-026-01086-5
