Thermocatalytic methane decomposition (TCMD) involving metal oxides is a more environmentally friendly and cost-effective strategy for scalable hydrogen fuel production compared to traditional steam reforming (MSR), as it requires less energy produces fewer CO/CO2 emissions. However, the unsupported oxide catalysts (such α-Fe2O3) that would be suited this purpose exhibit poor performance in TCMD. To overcome issue, novel was developed part of work, whereby oxygen vacancies (OVs) were...
