Catalyst 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.
1. A catalyst for selectively chemically reducing CO 2 to form CO, comprising:
a metal oxide having a chemical formula of Fe x Co y Mn (1-x-y) O z ,
wherein 0.7≤x≤0.95, 0.01≤y≤0.25, and z is an oxidation coordination number.
2. The catalyst as claimed in claim 1 , further comprising a support, and the metal oxide is loaded on the support.
3. The catalyst as claimed in claim 2 , wherein the support comprises zirconium oxide, titanium oxide, silicon oxide, zeolite, aluminum oxide, or a combination thereof.
4. The catalyst as claimed in claim 2 , wherein the metal oxide and the support have a weight ratio of 1:0.01 to 1:9.
