Herein, ethanol (C₂H₅OH) sensing properties of nanocrystalline copper oxide (CuO) nanoplates were investigated. The resistive chemi-sensor devices based on CuO nanoplates were fabricated for the enhanced and selective sensing of ethanol gas. The fabricated sensor exhibited a high ethanol response of 176 % towards ethanol gas concentration of 100 ppm at 250 ˚C. At optimized reaction conditions, in presence of various gases, i.e. NO₂, CO₂, CH_4, and H₂, the response of the fabricated sensor was highest which confirmed the high-selectivity. The fabricated CuO nanoplates based gas sensor was also employed for transient ethanol response and stability.

在此，研究了纳米晶氧化铜（CuO）纳米板的乙醇（C ₂ H ₅ OH）感测特性。制造了基于CuO纳米板的电阻式化学传感器设备，以增强和选择性地检测乙醇气体。制成的传感器在250°C时对100 ppm的乙醇气体浓度表现出176％的高乙醇响应。在优化的反应条件下，在各种气体（即NO ₂，CO ₂，CH ₄和H _{2）存在下}，所制造传感器的响应最高，这证实了其高选择性。所制造的基于CuO纳米板的气体传感器也用于瞬时乙醇响应和稳定性。
