采用喷雾热解法合成了 La0.8Sr0.2Al1−xMnxO3 (x = 0, 0.2, 0.4, 0.6)，作为氧化锆基电流型 NOx 传感器在高温还原气氛中稳定的传感电极（SE）材料。 La0.8Sr0.2AlO3氧化物在还原气氛中(4vol.% H2，750℃，2h)处理后的XRD衍射图与制备的相同。使用处理后的氧化物作为SE的传感器对500ppm NO 2 的响应为-1.3μA，该值大约等于使用处理前的氧化物获得的值。 © 日本电化学会，保留所有权利。
La0.8Sr0.2Al1−xMnxO3 (x = 0, 0.2, 0.4, 0.6) were synthesized using a spray pyrolysis method as a stable sensingelectrode (SE) material in high-temperature reducing atmosphere for zirconia-based amperometric NOx sensor. The XRD diffraction pattern of the La0.8Sr0.2AlO3 oxide after treatment in a reducing atmosphere (in 4vol.% H2 at 750°C for 2h) was same with the one as-prepared. A response to 500ppm NO2 of a sensor using the oxide after treatment as an SE was −1.3μA, a value approximately equal to that obtained using an oxide before treatment. © The Electrochemical Society of Japan, All rights reserved.
