摘要：

In this paper. CuO nanosheets were synthesized via hydrothermal process and efficiently utilized as redox mediator for the fabrication of efficient ethanol chemi-sensor. The morphological investigation of synthesized CuO products were analyzed by field emission scanning electron microscopy (FESEM) which confirmed that the synthesized products are sheet-shaped and are grown in large quantity. The detailed structural, compositional and optical characterizations of the synthesized nanosheets were done by X-ray diffraction (XRD) pattern, Fourier transform infrared (FTIR) and UV-vis spectroscopy, respectively which confirmed that the obtained nanosheets are well-crystalline pure CuO and possessing good optical properties. The fabricated ethanol sensor based on CuO nanosheet exhibits good sensitivity (similar to 0.9722 mu A.cm(-2).mM(-1)) and lower detection limit (0.143 mM), with linearity (R = 0.7806) in short response time (10.0 s).
