title: Acetone sensor based on solvothermally prepared ZnO doped with Co3O4nanorods.
abstract: This paper describes a reliable and sensitive method for sensing dissolved acetone using doped nanomaterials. Large-scale synthesis of ZnO nanorods (NRs) doped with Co3O4was accomplished by a solvothermal method at low temperature. The doped NRs were characterized in terms of their morphological, structural, and optical properties by using field-emission scanning electron microscopy coupled with energy-dispersive system, UV-Vis., Fourier transform IR, X-ray diffraction, and Xray photoelectron spectroscopy. The calcinated (at 400 °C) doped NRs are shown to be an attractive semiconductor nanomaterial for detecting acetone in aqueous solution using silver electrodes. The sensor exhibits excellent sensitivity, stability and reproducibility. The calibration plot is linear over a large concentration range (66.8 μM to 0.133 mM), displays high sensitivity (~3.58 μA cm-2mM-1) and a low detection limit (~14.7 ± 0.2 μM; at SNR of 3). FigureThe present study describes a simple, reliable, accurate, sensitive, and cost effective method for the detection of acetone using solvothermally prepared semiconductor co-doped nanomaterials.
