| چکیده | ||
| This paper reviews different method for synthesis of SnO2 and their nanocomposites with various morphologies as well as the study of sensing properties of these materials. The sensing properties of these materials depend not only upon the individual components used but also on the morphology, particle size and the interfacial characteristics. Depending on the chemical nature of the analyzed gas and the electronic structure of this metal oxide, such interactions can result in either an increase or a decrease of the sensory effect. Thus, by varying the electronic structure of this metal oxide composite sensor as well as the morphology and size of the SnO2 nanoparticles, the inherent characteristics of the sensor can be changed and tailored for detection of various gases. Such findings clearly open up new opportunities for development of novel selective sensors. In this brief review, attention will be focused on changes of morphology and composition of SnO2 that show dramatical effect on sensitivity of this material. | ||
