Research Abstract |
The performance of the present gas-sensors is based on the change of electric conductivity which is affected by the adsorption of electron-donor gases such as H_2S and mercaptan on the surface of the electrodeposited perylene film. It was confirmed that the present gas-sensors were detectable to low concentration of H_2S or mercaptan. The sensing properties to H_2S and. mercaptan were also investigated using soluble perylene derivatives. It was confirmed that low concentrations of H2S and mercaptan was detectable by the gas-sensor at room temperature and the current responses to the existence of H_2S and mercaptan were considerably quick These results suggest that adsorption and desorption of H_2S or mercaptan on the surfaces of film is easily achieved at room temperature. On and Co phthalocyanine films on indium/tin oxide (ITO) coated glass electrodes were prepared by cathodical polarization of the electrolytic solution containing CaCl_2 as a supporting electrolyte with a constant current The performance of the present gas-sensors is based on the change of electrical conductivity which is affected by the adsorption of acceptor gases such as NO_2 and SO_2 on the surface of the phthalocyanine film. It was confirmed that the present gas-sensors were detectable to ppm levels of NO_2 or SO_2.
