Abstract
Metal oxides are the class of materials having the widest application in gas sensors. This chapter presents information related to the application of various metal oxides in gas sensors designed on different principles. In particular, in the present chapter one can find descriptions of solid electrolyte hydrogen and oxygen electrochemical sensors, metal oxide heated chemirestors, p–n homojunction and heterostructure-based sensors, room temperature gas sensors, pyroelectric-based gas sensors, thermoelectric gas sensors, optical gas sensors based on chemochromic materials, etc. Criteria for metal oxides application in these devices are given. A comparative analysis of metal oxides is presented, and advantages and disadvantages are discussed. The chapter includes 37 figures, 22 tables, and 399 references.
