Hydrogen-based steelmaking gets 2x boost from nickel oxide catalyst, study finds
Steel and metal production are among the largest contributors to global greenhouse gas emissions, accounting for approximately 10% of global CO2 emissions.
AI Summary
Researchers at the Max Planck Institute for Sustainable Materials found that adding specific metal oxides as catalytic precursors can double the reduction kinetics of hydrogen‑based metal production compared with uncatalyzed processes. The study shows that the catalysts enable faster reduction of metal ores at temperatures below 800 °C, potentially lowering energy use. The findings were published in the journal Nature Synthesis.
