Abstract: 
Today, regarding to the air pollution caused by the smoke of cars and factories, measurements should be taken to detect and monitor the release of these contaminating compounds. Use of semiconductor metal oxide sensors is one of the methods for detecting of these compounds. These metal oxide gas sensors have many advantages, such as low cost and easy production, for detecting gases in domestic, commercial, and industrial applications. However, the performance of these sensors depends on a variety of factors, including the nature of the structure, morphology, doped additives, their structures, and so on. The most important of these sensors is tin dioxide. Therefore, in this review, the effects of various additives, including metal, metal oxide, and carbon, are investigated on the sensing properties of tin dioxide. The results revealed that these additives affect morphology, sensitivity, selectivity, response speed, and response temperature.
