“…Moreover, it was seen that a pure SmFeO 3 -based sensor operates under a high operating temperature of more than 400 °C, which could be reduced significantly to 150 °Cby substituting Fe atoms with Co atoms (SmFe 0.7 Co 0.3 O 3 ), enhancing its practicality. 83 The work suggested the further optimization of the SmFe 0.7 Co 0.3 O 3 material's properties for improved gas sensing performance.…”

“…It remains challenging to identify sensing materials for selective CO detection at lower operating temperature (\200°C). As tabulated in Table 1, the available sensing materials for low concentration CO detection can be grouped into three categories [1][2][3][4][5][6][7][8][9][10][11][12][13]. First, one can choose sensing materials based on their chemical composition and crystal structure.…”

In the present work we have investigated the carbon monoxide (CO) sensing characteristics of cobaltmodified lanthanum iron oxide perovskite sensors. Nanoparticles of lanthanum ferrite and cobalt-modified lanthanum ferrites have been synthesized by auto-combustion route. We have reported that Co-modified LaFeO 3 sensor is capable to sense low-concentration (\100 ppm) CO selectively at operating temperature as low as 100°C. The selective CO sensing characteristics at lower operating temperature are correlated to the superior catalytic activities of these perovskite toward CO oxidation. For these perovskite sensors it was demonstrated that the lower metal-oxygen binding energy, favorable d orbital electron configuration of transition metal cation/(s), and the nature of surface composition are the three dominant factors that control the catalytic activity and thereby the CO sensing characteristics.
