From: Upgrading CO2 to sustainable aromatics via perovskite-mediated tandem catalysis

Fig. 1

Atomic structural model of (a) Fe2O3, (b) Fe3O4, (c) ZnFe2O4, and (d) LaFeO3, showing different connection modes of [FeO6] octahedra. Spheres in red, brown, silver, and green represent O, Fe, Zn, and La atoms, respectively. e Fe–Fe distances of Fe, Fe carbides, and various Fe oxides. f Projected density of states (PDOSs) of Fe2O3, LaFeO3, and ZnFe2O4. g Calculated formation energies of per mole Fe5C2 through the reduction of Fe2O3, ZnFe2O4 and LaFeO3 by typical reactive atmospheres.
