Using operando XRD to identify the role and nature of Fe Carbide species for methane pyrolysis

The performance of methane pyrolysis catalysis is strongly influenced by the nature and properties of the supported metal however their exact relationship is still unknown. Of the most successfully applied metals for this reaction, Fe-based catalysts are considered the most robust, environmentally friendly and earth abundant. Fe has though a tendency to form a wide range of poorly crystalline carbides (FexCy where x > y and 1
