SnO2nanoparticles mixed with different amounts of gold nanoparticles (GNPs) were synthesized and their CO sensing properties were investigated. The sol–gel method was employed to prepare the initial solution. SEM, TEM, XRD, DLS and spectrophotometry were used to characterize the nanoparticles. The pure sensors showed a response of about 4 to 12.8 for (20–80)×10−6CO at operating temperature of 340 °C. The response and recovery time at 50×10−6Co is about 10 and 14 s, respectively. The amount of GNPs optimized was used to create high performance GNP-SnO2sensors (m(Au)/m(Sn)=3.7663×10−4) and optimal operating temperature was about 260 °C and the response at concentrations of (20–80)×10−6was 8.3 to 29.5, respectively. |
