A novel flake composite benzenoid-like CuFeO2@RGOwassuccessfullysynthesized.
The Fenton-like CuFeO2@RGO composite possessed highly catalytic activity of H2O2.
Both Cu(I) and Fe(III) were active centers of hexagonal CuFeO2 nanocrystals.
The composites had the advantages of easy recycling and good stability.
