| 제목 | The development of a sensor using TiO2 nanotube |
| 초록 | 1D titanium dioxide nanostructures, especially nanotubes are one of the most widely studied material due to its wide applications in photocatalytic, gas-sensing and optoelectronics. In this paper, a novel method for growing highly ordered TiO2 nanotubes(TNTs) arrays is demonstrated. Using an aluminum substrate(because of Al was electroplated on Ti thin foil) and the target by DC magnetron sputtering for several hours. Synthesis of TiO2 nanotubes by electrochemical anodization method in 0.5% NH4F solution using a DC power supply at 50V, room temperature. To make highly ordered TiO2 nanotubes arrays the effect of substrate and growth time has been studied systematically. The results show that the formation of TiO2 nanotubes was very sensitive to the anodizing time and the length of the tube increases with increasing in anodizing time. The surface morphology and crystal structure, properties were characterized by Scanning electron microscopy (SEM), Atomic force microscopy (AFM) and (XRD) X-Ray diffraction (XRD). The prepared TiO₂ nanotubes were fabricated for gas sensor for the detection of gas. The sensing properties of TiO2 nanotubes were studied at different gas concentration levels and operating temperatures.
