Abstract:
The porous Co3O4 nanowires were fabricated using a fluoride anion-assisted hydrothermal and controlled annealing route. The nanowires showed superior CO gas-sensing performances, such as high selectivity against CO and optimal sensing activity at a relatively low operating temperature (Top ≤ 100 °C). Such properties were ascribed to fluoride doping and porous nanowire structure.
