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 (T_op ≤ 100 °C). Such properties were ascribed to fluoride doping and porous nanowire structure.
