Zusammenfassung:	•HAp nano-rods were successfully synthesized from mussel shells.•Sonochemical technique provides rapid and facile conversion process.•HAp nano-rods exhibited 30–80nm in length and 12–18nm in width.•Photodegradation of 86.8% Rhodamine B was achieved after 300min of UV illumination. 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 300min in the presence of the HAp nano-rods photocatalyst.
