“…In this study, we used Cr 2 O 3 as the sensing electrode system, primarily because previous studies have shown that several compounds of chromium demonstrate high sensitivity [4,25]. For metal oxide electrodes, it is well recognized that the response for NO and NO 2 are usually in opposite directions with the NO 2 response being larger [7] as seen in Fig.…”

“…[6], NiCr204 [7], ZnFe204 [8] and ZnCr204 [9,10], since our first report in 1996 [3] suggested that the use of oxide SE in this type of NOx sensor is very effective for sensitive detection of NO2 at high temperatures. Several papers [14][15][16][17][18] dealing with oxides as a sensing electrode of mixed-potential-type NOx sensor have also been published by several research groups after our first report in 1996.…”

“…Several papers [14][15][16][17][18] dealing with oxides as a sensing electrode of mixed-potential-type NOx sensor have also been published by several research groups after our first report in 1996. Specifically, we investigated the zinc-family oxides as SEs for NO~ sensors [8][9][10]. Consequently, we have found that, among the single-type oxides examined, the ZnO-SE is most stable and gives the highest sensitivity to NOx at temperature as high as 700 ~ Therefore, in this study the main sensing properties of the YSZ-based mixed-potential NOx sensor using ZnO-SE have been investigated.…”

Abstract. Electrochemical sensors using tubular yttria-stabilized zirconia (YSZ) and oxide sensing electrode (SE) were fabricated and examined for NOx detection at high temperatures. The mixed-potential-type NOx sensor using ZnO-SE gave the highest sensitivity to NOx among other single-type oxides tested as SEs in the temperature range of 600-700 ~ The response of the ZnOattached device was a linear for the logarithm of NO2 (NO) concentrations from 40 to 450 ppm. The sensing mechanism of the sensor was discussed on the basis of the gas adsorption-desorption behavior, the catalytic activity data, and electrochemical behavior for oxides examined.

“…The emf values associated with metal oxides indicate that ZnFe 2 O 4 is best at differentiating NO 2 and NO among many other spinel-type oxides (5). Using impedance measurements, a ZnCr 2 O 4 -based electrode has been used to detect the total NO x content at 700ºC (6).…”

SRI International (SRI) is developing ceramic-based microsensors to detect exhaust gases such as NO, NO 2 , and CO in advanced combustion and gasification systems under this DOE NETL-sponsored research project. The sensors detect the electrochemical activity of the exhaust gas species on catalytic electrodes attached to a solid state electrolyte and are designed to operate at the high temperatures, elevated pressures, and corrosive environments typical of large power generation exhausts. The sensors can be easily integrated into online monitoring systems for active emission control. The ultimate objective is to develop sensors for multiple gas detection in a single package, along with data acquisition and control software and hardware, so that the information can be used for closed-loop control in novel advanced power generation systems.This report details the Phase I Proof-of-Concept, research activities performed from October 2003 to March 2005. SRI's research work includes synthesis of catalytic materials, sensor design and fabrication, software development, and demonstration of pulse voltammetric analysis of NO, NO 2 , and CO gases on catalytic electrodes.
