本研究以含浸法製備雙金屬氧化物複合材料 In2O3-WO3，將感測材料塗附於網印金電極的氧化鋁基板上作為一氧化氮感測器。在實驗中，藉由混合 In2O3 和 WO3 時重量百分比的改變，以及摻雜鉑金屬的量與鍛燒溫度的變化，以得到對一氧化氮有最佳感測效果的材料。本研究也利用了穿透式電子顯微鏡(transmission electron microscope, TEM) 對感測材料進行定性分析。

This study was using impregnation method to fabricate bimetal oxides In2O3-WO3, the sensing materials were covered in a screen printing gold electrode on alumina substrate as a nitric oxide sensor. In the experiment by change the amount of In2O3 and WO3 to get various weight ratios and we change the amount of platinum doping and calcinations temperature to get the sensing material which has the best sensor response of nitric oxide sensing. The prepared samples were characterized by transmission electron microscope (TEM) techniques.
