Core–shell structured composites of Zn-doped CoFe2O4 cubes @CNTs were in situ synthesised using a CVD method at 450°C with Zn-doped CoFe2O4 cubes as catalysts and ethanol as carbon source. The as-obtained products were characterised using an X-ray diffractometer, transmission electron microscope, th...
