摘要:
A tubular type sensor utilizing NASICON and a couple of metal oxide sensing electrodes was designed for detecting NH3and C7H8simultaneously. Here, NASICON was synthesized by sol-gel process For detectingNH3and C7H8, C-doped C2O3and ZnO-TiO2were used for the sensing electrodes, respectively Good linear correlations between the EMF values of the sensor and the logarithm of the concentrations for 50-500 ppm NH3and 5-50 ppm C7H8 were obtained at 250-400 degrees C The sensitivities of the sensor toNH3and C7H8were -91 and -60 mV/decade, respectively at 350 degrees C. Moreover, the sensor exhibited well selectivity and rapid response-recovery characteristics toNH3and C7H8.
