“…The peaks at 609 cm −1 and 443 cm −1 are related to Ti-O bond-stretching modes and the liberation of an oxygen atom in the direction of the c-axis. 23 It is worthy of note that the intensity of the peaks at 609 cm −1 and 443 cm −1 is much greater than the intensity of the peaks at 244 cm −1 and 144 cm −1 . This result shows that the TiO 2 NPs have good crystal quality, with few structural defects.…”

This study produces TiO 2 nanoparticles (NPs) using ultrasonic wave grinding technology. The experimental results show that the average diameter of TiO 2 NPs is about 75 nm. The micro-Raman spectrum shows that the crystal quality of these TiO 2 NPs is good. The TiO 2 NPs are integrated with a ZnO/MEMS structure to form a MEMS NO 2 gas sensor. Sensor response increases initially, reaches a maximum at 150 °C and then begins to decrease as the operational temperature is increased from 130 °C to 190 °C. The sensor response is increased when the concentration of NO 2 gas is increased.
