The facile synthesis, properties and application of ZAO nanomaterials

Aluminium-doped zinc oxide (ZAO) nanocrystals with uniform size, high purity and good degree of crystallinity were prepared by an ultrasonic–microwave assisted method. The structure, optical properties and morphologies of ZAO nanocrystals were characterised by X-ray powder diffraction, ultraviolet-visible spectroscopy, Fourier transform infrared spectroscopy and transmission electron microscopy, while the photocatalytic and anticorrosive effects of the product were studied by the degradation test of rhodamine B and salt spray corrosive test, respectively. The effects were quite satisfactory.
