Copper oxide CuO/tetragonal CuFe2O4 nanocomposites have been synthesized via the simple microemulsion route by addition of different Fe3+ ion ratios (where Fe3+ content=0, 0.05, 0.10, 0.15 and 0.20). It is clear that the pure CuO phase was observed from the precipitated copper hydroxide precursor at pH 12 as prepared and annealed at 600 to 800°C for 2h. Meanwhile, Fe3+ addition at low substitution...
