| Abstract: | ith sodalite as a gas-sensitive solid electrolyte and silver glass as an auxiliary gas-tigat solid electrolyte, a solid state electrochemical cell is constructed.A chemical sensor capable of detecting NO2,gas is realized by means of voltammetric measurement.The operation principle of the new sensor is discussed according to preliminary experimental results. Preliminary results show that the response sensitivity of the sensor increases with the increase of pre-reaction time and working temperature.Optimal responses can be achieved at a scanning rate of 200 mV/s voltage.The output of the sensor is found to be related to NO,partial pressure.It demonstrates the feasibility of detecting NO2 gas by means of solid state voltammetric measurement. |
