In this paper, we report the first synthesis of hydroxyapatite (HAp) nano-rods derived from mussel shells by a facile sonochemical method. HAp nano-rods were characterized by X-ray diffraction (XRD), Transmission electron microscopy (TEM), and Fourier transform infrared spectroscopy (FT-IR). The photocatalytic activity of HAp nano-rods was investigated using Rhodamine B (RhB) dye for the first time. The results confirm that degradation efficiency of 86.8% for RhB was observed after 300 min in the presence of the HAp nano-rods photocatalyst. © 2017 Elsevier B.V.
