摘要：

Herein, the fabrication and characterization of highly sensitive and selective ethanol gas sensor based on CuO nanodisks is reported. The CuO nanodisks were synthesized by facile hydrothermal process and detailed characterization revealed the well-crystallinity, high-purity and high density growth of the prepared material. To fabricate the ethanol gas sensor, the prepared nanodisks were coated on alumina substrate. The fabricated sensor exhibited high-sensitivity and the recorded gas response (resistance-ratio), response time (tau(res)) and recovery time (tau(recov)) were 6.2, 119 and 35 s, respectively for 100 ppm of C2H5OH at 300 degrees C. Further, the fabricated sensor shows high selectivity towards ethanol gas compared to H-2 and CO gases.
