Synthesis of SnO2 single-layered hollow microspheres and flowerlike nanospheres through a facile template-free hydrothermal method
Source abstract
Abstract
Abstract SnO2 single-layered hollow microspheres and SnO2 flowerlike nanospheres have been fabricated by one step template-free hydrothermal reaction with the help of PEG400. The concentration of NaOH plays an important role in the formation of SnO2 nanostructure. When the molar ratio of SnCl4/NaOH is 1:6, the nanostructure of SnO2 turns out to be a single-layered hollow microsphere. And it will be a flowerlike nanosphere when molar ratio of SnCl4/NaOH is 1:8. These single-layered hollow microspheres with diameters of 1–5 μm have a very thin shell thickness of about 200 nm. These flowerlike nanospheres with diameters of 0.5–1 μm are composed of SnO2 submicron rods with diameters of 200–300 nm. A possible growth mechanism is proposed.
