Abstract

High-density and uniform CuO nanostructures are synthesized via the facile oxidation of Cu foil in aqueous NH₄OH below 80 °C. The CH₃COCH₃ sensing properties of the synthesized materials are investigated at the operating temperature of 200–360 °C. A good sample is further tested with C₂H₅OH and NH₃ for demonstrating the gas selectivity at the optimal operating temperature. The selectivity between acetone and ethanol of the CuO nanowalls synthesized using this method is considered and compared with the results obtained by other studies.
