摘要：
In this work, we report the synthesis of nickel cobaltite/polyaniline (NiCo2O4/PANI) composite nanofiber for room temperature ammonia sensing. NiCo2O4 nanofibers and NiCo2O4/PANI composite nanofibers were prepared by electrospinning and in-situ polymerization. The surface morphology, elemental composition and structural analysis were done using SEM-EDX, XRD, and FTIR spectroscopy. SEM-EDX and XRD revealed the morphology, chemical composition, and crystallinity of nanofibers. FTIR confirmed the presence of functional groups in the composite. The unique features of both PANI and NiCo2O4 spinel nanostructure exhibited p-type heterojuction behaviour leads to ultrahigh sensing response for wide range from 500 ppm to 1 ppm of ammonia with good selectivity at room temperature.
