Highly Sensitive Pure and Pd-Doped LaFeO₃ Nanocrystalline Perovskite-Based Sensor Prepared by High Energy Ball Milling

Abstract:

Pure nanostructured LaFeO₃ with crystallite size of around 13 nm and specific surface area of 48 m²/g were prepared using high energy ball milling. 0.4, 2 and 5 wt% of Pd was impregnated on synthesized LaFeO₃. TPD-O₂, TPD-CO and TPR-H₂ were performed to find the effect of Pd loading on perovskite oxide properties.CO gas sensing properties of doped and pure formulation were investigated. These results showed that 2 wt% Pd had optimum response ratio which had a maximum response ratio of 1200% with respect to 100 ppm CO in air at 140°C.
