Spent Iron-Char Catalysts Are Not Waste: A Viewpoint on Integrating Methane Pyrolysis with Steelmaking

Abstract Methane pyrolysis offers a CO2-free pathway to hydrogen production; however, its commercial deployment remains hindered by a stoichiometric constraint: each kilogram of H2 co-produces three kilograms of solid carbon, which rapidly deactivates the catalyst. Conventional s...
