| description | TiO<sub>2</sub> nano-film type gas sensor has the advantages of simple preparation method, high sensitivity, good consistency and miniaturization, and the wide band of TiO<sub>2</sub> semiconductor enables it to greatly improve the performance of the sensor by coating other elements. Nowadays, it has received more and more attention from researchers. In this paper, the research progress of TiO<sub>2</sub> gas sensor at home and abroad was reviewed. The application of TiO<sub>2</sub> thin film gas sensor in the detection of six common reducing gases(H<sub>2</sub>, NH<sub>3</sub>, H<sub>2</sub>S, VOC, CO, SO<sub>2</sub>) and two common oxidizing gases(CO<sub>2</sub> and NO<sub><i>x</i></sub>) was introduced. In the application of gas detection, the sensing performance and sensing mechanism were discussed and the future research and development of TiO<sub>2</sub> thin film gas sensor were prospected such as doping conductive particles, precious metals or metal oxides into TiO<sub>2</sub> to improve its performance, which provides a reference for the study of new gas sensor. |
