چکیده انگلیسی
We have developed a planar type NOX sensor with a dense sensing layer that consists of nano-size grains and a reference electrode buried in an electrolyte by a pulsed laser deposition method, and examined for the mixed-potential-type NOX sensor. This sensor shows a high NO sensitivity at low temperature (300-450 °C). Electromotive force (EMF) values were almost linear to the logarithm of NO concentration, and the response was reproducible. The magnitude of EMF response was about â 90 mV upon exposure to 1000 ppm of NO at 350 °C. And, the 90% response and recovery times were found to be about 5 and 25 s at 450 °C, respectively. This cell opens up the possibilities for development of an integrated electrochemical device for NOX gas treatment in combustion exhausts.
