Characteristics and sensing properties of CO gas sensors based on LaCo<inf>1 − x</inf>Fe<inf>x</inf>O<inf>3</inf> nanoparticles
2017, Solid State IonicsCitation Excerpt :Therefore, LaFeO3 can also be a favorable material for CO sensing at low temperatures. In fact, LaFeO3 has been used to detect CO, for example, La0.9 − 0.1FeO3 ceramic powder showed response to 100 ppm CO at 100 °C [13]. Based on the above analyses, LaCo1 − xFexO3, a solid solution of LaCoO3 and LaFeO3, could be very promising for the CO sensing at low temperatures; there must be an optimal x value for obtaining the best CO sensing performance at low temperatures.

2015, Sensors and Actuators, B: ChemicalCitation Excerpt :Various perovskite oxides exhibit good CO gas sensing characteristics and catalytic CO oxidation activity. Table 4 [21–28] compares the CO sensing and its catalytic oxidation characteristics of various perovskite oxides with the work presented in this manuscript. Unlike all the tabulated reports, for LaFeO3 and LaFe0.8Co0.2O3, we have reported both sensing and catalytic oxidation characteristics of CO oxidation in the present manuscript.

2014, Sensors and Actuators, B: ChemicalCitation Excerpt :It has been further pointed that when exposed to 100 ppm CO, La0.9□0.1FeO3 (here □ represents La vacancy) nanocrystalline powders exhibits two response peaks in the response vs. temperature curve. One peak is at about 100 °C and another one is at about 260 °C [45]. The later peak in response may be connected with the effect of La vacancies.
