چکیده انگلیسی
In this paper, a novel highly-selective NH3 sensor based on a potassium trisoxalateferrate(III) complex was fabricated. Its gas-sensing properties were first investigated to NH3, H2S, NO2, SO2 and some organic solvent vapors. The sensors exhibited a high response to NH3 in a wide temperature range from room temperature to 150 °C. No responses were observed to H2S, NO2, SO2 and organic solvent vapors. The investigation proved that the response to NH3 was variable with the operating voltage. The optimum operating voltage was 5 V. The response and recovery time were about 1.8 and 1.5 min, respectively. Since this sensor has an excellent selectivity, it appears promising for a range of gas-sensing applications.
