High performance ethanol sensor for control drunken driving based on flame-made ZnO nanoparticles
ZnO nanoparticles were produced by FSP using zinc naphthenate as a precursor dissolved in toluene/acetonitrile (80/20 vol%). The phase and crystallite size were analyzed by Xray diffraction (XRD), and the specific surface area (SSA) of the nanoparticles was measured by nitrogen adsorption (BET analy...
