Enhanced ethanol selectivity of flame-spray-made Au/ZnO Thick Films
Copyright © 2014 American Scientific Publishers All rights reserved. Sensing characteristics of the spin-coated Au/ZnO nanoparticles thick films with different Au concentrations have been studied for various gases, namely, CO, SO2, ethanol and acetone. The influence on a dynamic range of Au concentr...

Phanichphant Chemical Engineering Chemistry Engineering Materials Science Physics and Astronomy Copyright © 2014 American Scientific Publishers All rights reserved. Sensing characteristics of the spin-coated Au/ZnO nanoparticles thick films with different Au concentrations have been studied for various gases, namely, CO, SO2, ethanol and acetone. The influence on a dynamic range of Au concentration on ethanol response (0.005-0.1 vol.%) of thick film sensor elements was studied at the operating temperatures ranging from 300 to 400 °C in the presence of dry air. The optimum Au concentration was found to be 0.5 mol%. 0.5 mol% Au exhibited an optimum ethanol response of 5.0 × 102and a short response time (10 s) for ethanol concentration of 0.1 vol.% at 400 °C. Plausible mechanisms explaining the enhanced ethanol selectivity by thick films of Au/ZnO are discussed. 2018-09-04T09:46:53Z 2018-09-04T09:46:53Z 2014-10-01 Journal 15334899 15334880 2-s2.0-84907638400 10.1166/jnn.2014.9430 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84907638400&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/53315 |
