Abstract
This paper presents synthesis, characterization and gas sensing properties of two dimensional nanostructures i.e. carbon nanoflakes (CNFs) grown by electro-phoretic deposition(EPD) on steel substrate using nitric acid refluxed electric arc synthesized carbon nanotubes(CNTs). Formation of CNFs has been confirmed by XRD and Raman spectra. Optical band gap measurement has been performed by UV-Vis spectroscopy. The morphology of CNFs has been studied via SEM. The EPD film has been characterized for gas sensing. The sensor responded to relatively low concentrations of liquefied petroleum gas (LPG) thus suggesting high-quality CNFs are useful for gas sensors. Sensor has shown maximum response at 200 °C.
