Microwave-assisted hydrothermal rapid synthesis of hydroxyapatite nanowires using adenosine 5'-triphosphate disodium salt as phosphorus source

摘要

Hydroxyapatite (HAP) is the most important inorganic constituent of biological hard tissues such as bone and tooth. However, the simple and controllable fabrication of HAP one-dimensional nanos-tructures remains a challenge. Herein, we report a microwave-assisted hydrothermal method for the rapid preparation of HAP nanowires using CaCl_2 · 2H_2O and adenosine 5'-triphosphate disodium salt hydrate (Na_2ATP) in aqueous solution without any surfactant. The effects of the reaction temperature and time on the morphology of the product are investigated. This method does not need any hard template or surfactant, avoiding the procedures and cost for their removal in the product. The as-prepared products are characterized by X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and transmission electron microscopy (TEM).
