Preparation and Characterization of SnO2 Nanospheres with Fine Structure

Abstract

Abstract: SnO₂ nanospheres with fine structure were prepared with SnCl₄·5H₂O as raw materials by a
solvothermal process. The X-ray diffraction pattern and selected area electron diffraction show that the as-prepared SnO₂ crystallites
are well crystallized. Transmission electron microscope micrographs show that the prepared product contains nanospheres with sizes of 50-80nm.
Magnified TEM image further reveals that the nanospheres display fine structure consisting of 2-6nm ultrafine particles. This structure tends to have high
specific surface area and favorable for the application in gas-sensitive detection.

Key words: oleic acid, preparation, nanocrystalline, tin oxide
