Abstract:
Different morphological Au@SbW9 nanostructures with potential biomedical applications were prepared under different concentration of NaOH at a definite molar ratio of Au(exp III): SbW9 = 2.0:3.5. The results showed that the concentration of NaOH strongly affected the morphology of Au@SbW9 nanostructures. By controlling the dose of NaOH, the morphology of the Au@SbW9 nanostructures could be controlled. When the concentration of NaOH increased from 2.5x10-4 M to 5.0x10-4 M, 7.5x10-4 M, 9.0x10-4 M, 10.5x10-4 M and 12.0x10-4 M, the morphology of Au@SbW9 nanostructures gradually changed from nanoflowers to nanonets, nanowires. In this process sodium hydroxide acted as a conditioning agent of Au(exp III)precursor activity. This work not only represented an approach to tune the morphology of Au@POM nanostructures with a simple method and convenient synthetic conditions, but also established a foundation for the potential biomedical applications of Au@SbW9 nanostructures.
