Catalyst-assisted chemical looping for CO2 conversion to CO

- Catalyst-assisted chemical looping for the transformation of CO2 to CO.
- Ni catalyst converts CH4 + CO2 into a syngas, which reduce CeO2-Fe2O3.
- The surface carbon gave rise to a higher yield of CO.
- Interaction of Ni with Fe during NiO reduced lead to formation of a Ni3Fe alloy.
- Ni3Fe alloy decomposed into Ni and Fe3O4 during CO2 re-oxidation.
