چکیده انگلیسی
A sensor to detect ozone in water was fabricated using coating film of single-wall carbon nanohorns (CNHs). This sensor is based on the phenomena that the electric resistance of the CNH-film decreased with the adsorption of ozone molecules thereon due to charge transfer from the surface of CNHs to O3 molecules. The shift of the electric resistance of the CNH-film was monitored with varied concentrations of aqueous ozone at several temperatures. The shift of the electric resistance of the CNH-film was correlated with the ozone concentration and temperature based on monolayer adsorption model with consideration of activation energies of the relevant adsorption, desorption, and sensitivity of charge transfer.
