Positive Effect

Highly efficient and effective porous ZnO nanorod arrays were fabricated by annealing ZnO nanorod arrays grown on a substrate using a simple hydrothermal method. The annealing had a positive effect on the nanorod morphology, structure and optical properties. The porosity was closely related to the annealing temperature. After heating at 450 °C, pores appeared on the nanorods. It was demonstrated that the porosity could be exploited to improve the visible light absorption of ZnO and reduce the bandgap from 3.11 eV to 2.99 eV. A combination of improved charge separation and transport of the heat-treated ZnO thus led to an increase in the photoelectrochemical properties. At an irradiation intensity of 100 mW/cm−2, the photocurrent density of the porous nanorod array was approximately 1.3 mA cm−2 at 1.2 V versus Ag/AgCl, which was five times higher than that of the ZnO nanorods. These results revealed the synthesis of promising porous ZnO nanorods for photoelectrochemical applications.

Bioi Nanosheets

A simple two-step method of growing ZnO nanorod arrays on the surface of BiOI nanosheets was developed under mild environment. The hierarchical structure of ZnO arrays@BiOI nanosheets was characterized by various measurements like X-ray powder diffraction, scanning electron microscopy, transmission electron microscopy, and energy-dispersive X-ray detector. The optical absorption of the ZnO arrays@BiOI nanosheets composite was investigated by UV-Vis diffuse reflectance spectra. The photocatalytic degradation of methanol orange under visible light shows that the obtained ZnO arrays@BiOI nanosheets heterostructures exhibit enhanced photocatalytic activity, contrasting to the sum of BiOI nanosheets and ZnO nanorods. The mechanism of the photocatalytic process was discussed. This method of growing ZnO nanorod arrays on other nanosheets also provides a potential method to fabricating other complex structures.

In this study, we fabricated the zinc oxide (ZnO) nanorods arrays by hydrothermal technique on indium doped tin oxide (ITO) substrate with different concentration of the precursor with zinc nitrate and hexamethyleneteramine (HMTA) in distilled water. Structure, morphology and optical properties of ZnOnanorods on ITO substrate were characterized by x-ray diffractometer, field-emission scanning electron microscope and spectrophotometer, respectively. The ZnO nanorod arrays showing preferentially oriented in the (001) direction and with a wurtzite structure. The scanning electron microscopy results showed that the hexagonal shape ZnO nanorods. It was found that the diameter, length and density of the ZnO nanorods arrays were strongly influenced by the precursor concentration.
