Mixed metal iron oxides and uses thereof
This invention is directed to novel mixed transition metal iron (II/III) catalysts for the extraction of oxygen from CO 2 and the selective reaction with organic compounds.
1. A method for converting a hydrocarbon to an oxygenated hydrocarbon which comprises contacting a mixed transition iron (II/III) metal catalyst for catalyzing CO 2 oxidation of the hydrocarbon, wherein the mixed transition metal iron (II/III) catalyst is an iron (II/III) and a second metal oxide selected from the group consisting of Ag, Bi, Co, Cu, La, Mn, Sn, Ru, and Zn, and an appropriate CO 2 feed stream under appropriate conditions so as to form the oxygenated hydrocarbon.
2. The method of claim 1 , wherein the hydrocarbon is an alkane, an alkene, an alkyne, an aromatic compound, a cyclic compound, a polyaromatic compound or a polycyclic compound.
3. The method of claim 2 , wherein the alkane is butane, ethane, methane, or propane.
4. The method of claim 2 , wherein the alkene is ethylene or propylene.
5. The method of claim 1 , wherein the oxygenated hydrocarbon is an alcohol, aldehyde, an anhydride, a carboxylic acid, an ester, an ether, an epoxide, or a ketone.
6. The method of claim 5 , wherein the epoxide is ethylene oxide or propylene oxide.
