ZrO2 Nanolif Oksijen Sensörünün Performans Değerlendirmesi

An alternative oxygen sensor to conventional ZrO2 based automotive sensors (COS) was successfully manufactured. nanoparticles were used as base material and nanofibers fabricated via electrospinning using polyvinyl alcohol solution (ZrO2+PVOH) obtain active surface of the where engine exhaust gas interacts chemisorption reactions take place prior calcination process at 700 oC. Thanks operating temperature control high surface/volume ratio nanofibrous structure, ZrO2+PVOH demonstrated similar performance with COS under increasing percentage (until 50-60%) along conditions. For sensor, maximum sensing (Ra/Re) 7.24 achieved oC concentration 50% whereas it 8.11 for EOS same The performed acceptable throughout wider range (270-900 oC) compared COS. Though an average 15% reduction in observed promising results this will be a good guide more comprehensive future works focusing on very rapid response-recovery time light-off capability.
