In this work, tin oxide nanostructures were synthesized using the solution combustion technique and its application as a paper-based flexible electrode is demonstrated for the first time for ammonia sensing applications. The synthesized tin oxide nanostructures are characterized by using X-ray diffraction (XRD), Field emission scanning electron microscopy (FE-SEM) with Energy dispersive X-ray spectroscopy (EDS), Fourier Transform Infrared Spectroscopy (FTIR), and Linear Sweep Voltammetry (LSV). XRD analysis confirms the tetragonal phase of the synthesized nanostructures. The field emission scanning electron microscope confirms the formation of nanoparticles, and EDS confirms the formation of nanoparticles without any impurity. FTIR shows the presence of O-H, C=O, Sn-OH, and Sn-O-Sn functional groups, also confirming the same. The electrical characterization of nanostructured layer coated on a Whatman paper-based electrode shows the detection of ammonia in humid air (with relative humidity of 52%) with respect to different exposure times. These studies lay a foundation for using tin oxide nanostructures for potential application as flexible, low-cost, and highly sensitive ammonia sensing devices.
