Facile synthesis of boscage-like SnO2 nanorods by hydrothermal method

Abstract Boscage-like SnO 2 nanorods were successfully synthesized by a facile one-step hydrothermal route only using the sodium stannate trihydrate solution of alcohol and water, without any surfactants and substrates. X-ray diffraction spectra, scanning electron microscopy, transmission electron microscopy and high-resolution transmission electron microscopy were used to examine the morphology and microstructure of SnO 2 nanorods boscages. The results show that the SnO 2 nanorods boscage consists of single crystalline, rutile SnO 2 nanorods with a diameter of 4–10 nm and length of about 200 nm. The formation and growth of the boscage-like SnO 2 nanorods can be rationally expressed by the Ostwald-ripening assisted oriented attachment mechanism as a kinetically controlled nonclassical crystallization process.
