Abstract
La-doped CuO nanosheets were prepared through a electrodeposition method in order to enhance their photocatalytic properties. X-ray diffraction pattern (XRD) and field emission scanning electron microscopy (FESEM) with energy dispersive spectroscopy (EDS) demonstrated that La3+ entered the crystal lattice of CuO and substituted Cu2+ without destroying crystal structures to form petal-like CuO nanostructures. The band gap of doped samples range between 1.10 and 1.30 eV. Better photocatalytic activity for the photodegradation of methyl blue than the pure CuO nanostructures, which is 11.5 % higher than that in undoped CuO.
