Abstract
PANI/Fe-doped CeO2 nanocomposite were synthesized by the in-situ process. The produced powders were characterized by XRD, XPS, FT-IR, Raman, HRTEM and SEM-EDS tests. The sensors function was based on PANI/Fe-doped CeO2 nanocomposite with thin film deposited on top of interdigitated electrodes (IDT). NH3 detection with PANI/Fe-doped CeO2 nanocomposite sensor could be successfully performed even at room temperature (RT) and relative humidity of 45%. Results demonstrated that PANI/Fe-doped CeO2 might be promising sensing materials for detecting of the low NH3 concentration (ppm). In addition, the sensor is selective to the interfering gases, including CO, CO2 and NO2. This sensor displays acceptable repeatability and stability over time.
