Abstract: A catalyst for methanation reaction and a method for preparing methane are provided. The catalyst for methanation reaction includes a core, a shell encapsulating the core, and an active metal. The core includes cerium dioxide (CeO2), the shell includes zirconium dioxide (ZrO2), and the active metal is in particle form and is disposed on an outer surface of the shell layer.

Abstract: A method for selectively chemically reducing CO2 to form CO includes providing a catalyst, and contacting H2 and CO2 with the catalyst to chemically reduce CO2 to form CO. The catalyst includes a metal oxide having a chemical formula of FexCoyMn(1-x-y)Oz, in which 0.7≤x≤0.95, 0.01≤y≤0.25, and z is an oxidation coordination number.

Abstract: A method for selectively chemically reducing CO2 to form CO includes providing a catalyst, and contacting H2 and CO2 with the catalyst to chemically reduce CO2 to form CO. The catalyst includes a metal oxide having a chemical formula of FexCoyMn(1−x−y)Oz, in which 0.7≤x≤0.95, 0.01≤y≤0.25, and z is an oxidation coordination number.
