摘要
A simple dissolution-renucleation process of SnC2O4 crystals was explored to prepare SnO2 nanostructures. By controlling supersaturation of SnC2O4 crystals, nucleus surface/solution interfacial energy, and other reaction parameters, including concentration of a reactant, volume of water, and the amount of poly(ethyleneglycol), a series of SnC2O4 nanostructures could be obtained. A dissolution-renucleation growth mechanism of the flowerlike SnC2O4 nanostructures was suggested and discussed in detail. The results showed that the poly(ethyleneglycol) played an important role in tuning the SnC2O4 nanostructures. Meanwhile, high concentration of SnCl2 in the mixed solvent of ethanol and poly(ethyleneglycol), and a large amount of water were favorable to the formation of the flowerlike SnC2O4.
