摘要

An in situ thermal oxidation strategy was proposed for synthesizing different SnO_2 nanostructures, using our homemade SnS_2 nanoplates as a precursor. The characterization results from X-ray diffraction, energy dispersive X-ray spectroscopy, and field emission scanning electron microscope revealed that the heating temperature played an important role in the microstructure and composition of the resultant products. By heating the SnS_2 nanoplates in air at 400, 600 and 800 ℃ for 5 h, nanoplates, a mixture of nanoplates and nanoparticles, and nanoparticles of SnO_2 were synthesized, respectively. The residual S was about 2.2 mol % in the product synthesized at 400 ℃, while no residual S was detected in the products synthesized at 600 and 800 ℃.
