The reverse water-gas shift reaction activity of iron carbide catalysts (Fe₃C, Fe₅C₂) with different crystal structures was investigated under atmospheric pressure. Fe₃C exhibited a higher CO generation rate than Fe₅C₂ and iron oxide, which mainly consists of Fe₃O₄. The comparison of activation energies suggested that the reaction mechanisms were different for the two iron carbide catalysts. Furthermore, it was found that the effect of pressure was also significantly different for the two iron carbide catalysts.
