Abstract

Strontium carbonate architectures assembled from nanorods are successfully synthesized at room temperature and screw capped method at 100 °C. Our experiments show that the protocol followed for the synthesis of SrCO 3 as well as the concentration of various gums used, play an important role in the size and morphology of SrCO 3 . Here in, we obtained aragonite nanorod aggregates with unusual morphologies via transformation of metal carbonates at different conditions using natural gums as additives. A rational mechanism based on the oriented self-assembly of SrCO 3 nuclei is proposed for the formed architectures. The crystals undergo an interesting morphology changes and have been well characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Thermogravimetric analysis (TGA) and Fourier Transform Infrared spectroscopy (FT-IR) techniques. This method is simple, low-cost and environmentally friendly route for the synthesis of SrCO 3 architectures with different morphologies.
