NO2 gas sensing of flame-made Pt-loaded WO3 thick films

NO2 gas sensing of flame-made Pt-loaded WO3 thick films

Unloaded WO3 and 0.25-1.0 wt% Pt-loaded WO3 nanoparticles for NO2 gas detection were synthesized by flame spray pyrolysis (FSP) and characterized via X-ray diffraction (XRD), scanning electron microscopy (SEM) and high resolution transmission electron microscopy (HRTEM). The BET surface area (SSABET...

Unloaded WO3 and 0.25-1.0 wt% Pt-loaded WO3 nanoparticles for NO2 gas detection were synthesized by flame spray pyrolysis (FSP) and characterized via X-ray diffraction (XRD), scanning electron microscopy (SEM) and high resolution transmission electron microscopy (HRTEM). The BET surface area (SSABET) of the nanoparticles was measured by nitrogen adsorption. The NO2 sensing properties of the sensors based on unloaded and Pt-loaded WO3 nanoparticles were investigated. The results showed that the gas sensing properties of the Pt-loaded WO3 sensors were excellent to those of the unloaded one. Especially, 0.25 wt% Pt-loaded WO3 sensor showed highest response to NO2 than the others at low operating temperature of 150 °C. © 2013 Elsevier Inc. 2014-08-30T03:51:43Z 2014-08-30T03:51:43Z 2014 Article 1095726X 10.1016/j.jssc.2013.10.041 JSSCB http://www.scopus.com/inward/record.url?eid=2-s2.0-84901038411&partnerID=40&md5=23c6013021eac25277861043d7f9bd64 http://cmuir.cmu.ac.th/handle/6653943832/7234 English Academic Press Inc.
