Abstract
N-doped Zr02 nanomaterials possessing heterogeneous structure were successfully prepared by a simple mechanochemical route. The physical characterization of the samples was performed using X-ray powder diffraction (XRD), UV-vis diffuse reflectance spectroscopy (DRS), Fourier transform infrared spectroscopy (FT- IR) and electron paramagnetic resonance (EPR). The observed results imply that intensive ball milling process had an effect on the transformation of Zr02 monoclinic phase into tetragonal one. The photocatalytic reactivity of the samples was investigated for the degradation of tetracycline hydrochloride (TCH) in an aqueous solution. In comparison to the nitrogen free sample, the N-doped Zr02 nanostructured photocatalyst exhibited higher photodegradation activity.
