Several trimetallic ferrites with different ratios of Cu, Fe, and Mn were synthesized by direct decomposition method and tested for chemical looping combustion of methane, synthesis gas, and carbon. For comparison, several bimetallic ferrites were also tested, and NiFe

, which had shown the best performance among the bimetallic ferrites for CLC of methane. From all the trimetallic oxygen carriers with different atomic ratios of Cu, Fe, and Mn, CuFeMnO

, even without a support, showed very stable performance during a 100-cycle TGA test. The CuFeMnO

is also suitable for CLC of a solid fuel, such as carbon, which showed stable performance during a 10-cycle test.
