“…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].…”

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.

“…For example, it was shown that for the configuration where the sensing (LaFeO 3 or WO 3 ) and platinum reference electrodes were placed on opposite sides of the electrolyte and both electrodes were exposed to the same gas environment, LaFeO 3 , a p-type semiconductor, and WO 3 , an n-type semiconductor, both exhibited positive responses when exposed to NO 2 and negative responses when exposed to NO , Di Bartolomeo 2000. Since both electrodes were exposed to the same gases, both reactions (Eqs.…”

“…Noticeably, catalyst with a Cu/Cr molar ratio of 0.7 exhibited promising catalytic activity with high burning rate and low pressure exponent at all pressures, due to the effective phase interaction between the spinel CuCr2O4 and delafossite CuCrO2 contained in the as-synthesized Cu-Cr-O nanocomposites. Patil, et al [320] synthesized p-type nano-CuO and CuCr2O4 by an electrochemical method and investigated the catalytic effect on the thermal decomposition behaviour of ammonium perchlorate (AP) as a function of catalyst concentration using differential scanning calorimetry. The nano-copper chromite (CuCr2O4) showed best catalytic effects as compared to nano-cupric oxide (CuO) in lowering the high temperature decomposition by 118 0 C at 2 wt.%.…”

In this review article various applications and preparation methods of copper chromite catalysts have been discussed. While discussing it is concluded that copper chromite is a versatile catalyst which not only catalyses numerous processes of commercial importance and national program related to defence and space research but also finds applications in the most concerned problem worldwide i.e. environmental pollution control. Several other very useful applications of copper chromite catalysts are in production of clean energy, drugs and agro chemicals, etc. Various preparation methods about 15 have been discussed which depicts clear idea about the dependence of catalytic activity and selectivity on way of preparation of catalyst. In view of the globally increasing interest towards copper chromite catalysis, reexamination on the important applications of such catalysts and their useful preparation methods is thus the need of the time. This review paper encloses 369 references including a well-conceivable tabulation of the newer state of the art.
