Aerogels Handbook

Part of the book series: Advances in Sol-Gel Derived Materials and Technologies ((Adv.Sol-Gel Deriv. Materials Technol.))

Abstract

Sensing of chemical species in air, in water and in other solvents is important for a wide variety of applications, including but not limited to monitoring chemical species that might have environmental, health, forensic, manufacturing, or security implications. The unusual properties of aerogels – very high surface area, high porosity, low density – render them particularly appealing for sensing applications. In this chapter, we survey the published reports of the application of aerogels to chemical sensing. These include sensors based on silica, silica composite, titania, carbon and clay aerogels, with spectroscopic and conductimetric detection methods.
