In recent years, many attempts have been made to improve the sensory properties of SnO2, including design of sensors based on one-dimensional nanostructures of this material, such as nanofibers, nanotubes or nanowires. One of the simpler methods of producing one-dimensional tin oxide nanomaterials is to combine the electrospinning method with a sol-gel process. The purpose of this work was to produce SnO2 nanowires using a hybrid electrospinning method combined with a heat treatment process at the temperature of 600 °C and to analyze the morphology and structure of the one-dimensional nanomaterial produced in this way. Analysis of the morphology of composite one-dimensional tin oxide nanostructures showed that smooth, homogeneous and crystalline nanowires were obtained. Full Text: PDF ReferencesN. Dharmaraj, C.H.
