Abstract
Highly Sensing Properties Sensors Based on Ce-doped ZnO and SnO2 Nanoparticles to Ethanol Gas
Highlights
The detection of different types of gases and quantification of their precisely concentration have wide applications in different fields like domestic gas alarms, medical diagnostic equipment, industrial safety, environmental pollution, military field and food industry [Papadopoulos et al (1996), Wang C et al (2009), Wetchakun et al (2011), Brudzewski et al (2012), Mielle et al (2001) and Fleming (2001)]
Ethanol gas sensors based on semiconductor metal oxide materials offer considerable advantages in comparison to other gas sensing methods [Korotcenkov 2007]
The current study aims to compare between the samples which exhibited the best sensing characteristics at the same conditions to define the high sensing properties sensors to ethanol gas among the two oxides sensors
Summary
The detection of different types of gases and quantification of their precisely concentration have wide applications in different fields like domestic gas alarms, medical diagnostic equipment, industrial safety, environmental pollution, military field and food industry [Papadopoulos et al (1996), Wang C et al (2009), Wetchakun et al (2011), Brudzewski et al (2012), Mielle et al (2001) and Fleming (2001)]. A comparative study on the sensing properties of nanoparticles ZnO+ x wt% CeO2 and SnO2+ x wt% CeO2 (x = 0, 2, 4 and 6) sensors sintered at 400 oC toward ethanol gas have been carried out.
