| Abstract: In this work, under the regulation of citric acid, SnO2 nanorods were synthesized by hydrothermal method. The structural characteristics of SnO 2 samples during the growth process was investigated by using high-resolution transmission electron microscope, X-ray diffraction, infrared spectra Fourier transform spectra, Brunauer-EmmettTeller nitrogen physisorption, UV-visible diffuse reflection spectrum, and photoluminescence spectra. The results reveal that the overall crystal growth can further be divided into two stages:the oriented attachment of SnO2 nanocrystals at the early stage and subsequently a slow crystal growth along the[001] direction following the Ostwald ripening mode. Photoluminescence property and photocatalytic activity of SnO2 nanoparticles at the different stages was also investigated, which show a similar changing trend with the crystal growing:greatly increased at the former stage and gradually decreased at the latter stage. |
