High-density and uniform CuO nanostructures are synthesized via the facile oxidation of Cu foil in aqueous NH4OH below 80 degrees C. The CH3COCH3 sensing properties of the synthesized materials are investigated at the operating temperature of 200-360 degrees 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. (C) 2018 Elsevier Ltd.
