Abstract
ZnO nanocrystals were prepared by a wet chemical method based on alkaline-activated 10 hydrolysis and condensation of zinc acetate solutions. With this procedure, the mean crystallite size of the obtained powders was found in the range from 2.5 to 4.5 nm. Drop casting of the nanocrystals onto alumina substrates allowed the fabrication of gas sensing devices. These Q-ZnO based gas sensors were tested towards NO2, acetone and methanol and gas sensing tests showed promising results compared with the ZnO thin and/or thick films gas sensors. © 2010 Springer Science+Business Media B.V.
