Preparation and characterisation of NH₃ gas sensor based on PANI/Fe-doped CeO ₂ nanocomposite.

ABSTRACT: PANI/Fe-doped CeO ₂ nanocomposite was synthesised by the in-situ process. The produced powders were characterised by XRD, XPS, FT-IR, Raman, HRTEM and SEM-EDS tests. The sensors' function was based on PANI/Fe-doped CeO ₂ nanocomposite with thin film deposited on top of interdigitated electrodes (IDT). NH ₃ detection with PANI/Fe-doped CeO ₂ nanocomposite sensor could be successfully performed even at room temperature (RT) and relative humidity of 45 %. Results demonstrated that PANI/Fe-doped CeO ₂ might be promising sensing materials for detecting the low NH ₃ concentration
