The products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman spectroscopy and Fourier-transform infrared spectroscopy (FTIR), and were specified as hexagonal wurtzite ZnO particles. Their photocatalytic activities were investigated through the degradation of methylene blue (MB) activated by UV radiation. In this research, 3 wt% Nd-doped ZnO showed the best significantly improved photocatalytic activity for degradation of MB dye of 3.95 × 10−3min−1. The photocatalysis of Nd-doped ZnO samples activated by UV radiation was also discussed.
