摘要

In this study, zinc oxide (ZnO) nanaords doped with different concentrations (0%, 1%, 2%) of aluminum (Al) were prepared by hydrothermal method. The effects of different concentrations of Al-doped ZnO nanorods on electrical properties and responses to different concentrations (0 mM to 12 mM) of glucose were investigated. The results show that Al-doped ZnO changes the energy gap of pure ZnO and enhances the carrier concentration. Nanorods also changes the surface area of the element due to the influence of doping. The preparation method is simple, safe and non-toxic. After the measurement results, the Al doping improves the sensitivity, stability and reliability of glucose. In the future, this research method can be used to enhance the non-enzymatic electrochemical sensor of glucose.
