Temperature controlled synthesis of SrCO_3 nanorods via a facile solid-state decomposition rout starting from a novel inorganic precursor

摘要

Strontium carbonate nanorods have been successfully synthesized via solid-state decomposition of a new precursor, [Sr(PhtXH_2O)_2]. The obtained nanorods were found to be orthorhombic with the length of 70-100nm and the diameter of about 10-15nm. The Effect of calcinations temperature on morphology and purity of the products has been investigated. Strontium carbonate nanorods were formed at 500℃ The products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Fourier transform infrared (FT-IR) spectroscopy. In addition, further evidence for the purity and stoichiometry of the product was obtained by XPS (X-ray photoelectron spectroscopy) spectrum.
