Novel Cu-based binary composite phases were synthesized with an octadecylamine (ODA) synthetic system. HR-TEM was used to characterize the binary composite phase indicating that the Cu-based binary composite phase was a mixed phase of two oxides. ZnO gas sensing films decorated with Cu-based binary composite phase were parallel fabricated. The gas sensing performance to nitric oxides (NO, N₂O, NO${}_2)$ was studied. Cu–Mo–O binary composite phase-modified ZnO was screened out with high sensitivity and selectivity to NO. The gas sensing response to 0.5 ppm NO was 128.1. The detection limit of Cu–Mo–O binary composite phase-modified ZnO to NO was less than 10 ppb. Cu–Mo–O binary composite phase-modified ZnO also shows good selectivity to NO even using NO₂ as interference gas. It is of great importance for the detection of NO.

采用十八胺（ODA）合成系统合成了新型铜基二元复合相。采用HR-TEM对二元复合相进行表征，表明Cu基二元复合相是两种氧化物的混合相。平行制备了铜基二元复合相修饰的 ZnO 气敏薄膜。对一氧化氮（NO、N ₂ O、NO${}_2）$被研究了。筛选出对 NO 具有高灵敏度和选择性的 Cu-Mo-O 二元复合相改性 ZnO。对 0.5 ppm NO 的气敏响应为 128.1。Cu-Mo-O二元复合相改性ZnO对NO的检测限小于10 ppb。_{即使使用NO 2}作为干扰气体，Cu-Mo-O二元复合相改性ZnO也对NO表现出良好的选择性。对NO的检测具有重要意义。
