Abstract:
Aero-gel based one-pot synthesis of anatase phase TiO2 nanoparticles having a high surface area of 125 m2 g-1 has been reported in this work. The humidity sensing perfomance of the obtained porous TiO2 nanoparticles exhibits a quick response (2 s) and fast recovery (1.5 s), negligible hysteresis (<1%) and good stability in the 11-98%RH range. The relationship between %RH and resistance was found to be linear while the sensitivity increases with increase in %RH.

Dehydration Synthesis
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.
