Operando Investigations of Rare-Earth Oxycarbonate CO<sub>2</sub> Sensors
In this work, we have succeeded in synthesizing monoclinic and hexagonal La<sub>2</sub>O<sub>2</sub>CO<sub>3</sub> using two different routes and revealed that both of them are sensitive to CO<sub>2</sub> to the same degree. Moreover, we observed that...

| description | In this work, we have succeeded in synthesizing monoclinic and hexagonal La<sub>2</sub>O<sub>2</sub>CO<sub>3</sub> using two different routes and revealed that both of them are sensitive to CO<sub>2</sub> to the same degree. Moreover, we observed that the resistance of the sensor based on hexagonal phase is much higher and more stable than the one of the sensors based on the monoclinic phase. Using Operando and time resolved XRD measurements, we have also demonstrated that the resistivity of the sensor based on monoclinic La<sub>2</sub>O<sub>2</sub>CO<sub>3</sub> increases because of the material transformation into the hexagonal phase during an exemplarily aging process. |
