Controlled Growth of SnO{sub}2 Micro/Nanocrystalswith Different Morphologies via a Solution Method

摘要

SnO{sub}2 nanocrystals with various morphologies were synthesized via a hydrothermal method assisting by the surfactant CTAB. The morphologies of the products were significantly dependent on the synthesis conditions. The products were characterized by X-ray diffraction (XRD) and field scanning electron microscopy (FESEM). The results showed products SnO{sub}2 nanoparticles and spheres like structure assembled with nanocones were obtained by varying the dosage of CTAB and the concentration of NaOH. The forming process of SnO{sub}2 sphere like structure was discussed and the proposed mechanism was put forward in this work.
