Method for selectively chemically reducing CO
A method for selectively chemically reducing CO 2 to form CO includes providing a catalyst, and contacting H 2 and CO 2 with the catalyst to chemically reduce CO 2 to form CO. The catalyst includes a metal oxide having a chemical formula of Fe x Co y Mn (1−x−y) O z , in which 0.7≤x≤0.95, 0.01≤y≤0.25, and z is an oxidation coordination number.
