摘要：
本发明提供一种氮氧化物传感器用铂金电极浆料，其特征在于，包含下列组成成分且各组成成分的质量百分比为：有机载体15～25％；二氧化锆1～5％；造孔剂1～5％；超细金粉0.1～1％；超细铂粉50～65％，本发明氮氧化物传感器用铂金电极浆料能实现贵金属电极与氧化锆陶瓷基体共烧，对NO2的分解具有很好的催化作用并且不分解NO，十分具有实用性。本发明还提供上述氮氧化物传感器用铂金电极浆料的制备方法，过程简单易行，有利于工业化生产，适于大规模推广应用。
摘要（英）：

The invention provides platinum electrode slurry for a nitrogen oxide sensor. The platinum electrode slurry is characterized by comprising, by mass, 15% to 25% of organic carriers, 1% to 5% of zirconium dioxide, 1% to 5% of pore forming agents, 0.1% to 1% of superfine gold powder and 50% to 65% of superfine platinum powder. By means of the platinum electrode slurry for the nitrogen oxide sensor, co-firing of a precious metal electrode and a zirconia ceramic substrate can be achieved, the good catalytic action on decomposition of NO2 is achieved, NO is not decomposed, and the practicability is high. The invention further provides a preparing method of the platinum electrode slurry for the nitrogen oxide sensor, the process is simple and easy to implement, industrial production is facilitated, and the platinum electrode slurry and the preparing method are suitable for large-scale application and popularization.
