Gas-sensing Properties of La_(0.68)Pb_(0.32)O_3 Nano-materials under Low Operating Temperature
Source abstract
Abstract
The La0.68Pb0.32FeO3 sample with an orthogonal perovskite structure was prepared by using the sol-gel method. The gas-sensing properties were studied in CO gas. The experimental results reveal that the La0.68Pb0.32FeO3 sample shows smaller grain sizes, higher conductance and higher sensitivity to CO gas, especially the much lower operating temperature compared with LaFeO3 sample. The activation energy for La0.68Pb0.32FeO3 sample in CO gas is higher than that in air.
