The stable molecular structure of chlorobenzene makes it difficult to detect at room temperature. In this study, potassium hydroxide and tetracyanonickelate (II) fabricated nickel foam was synthesized using a dip-coating method and monitored the chlorobenzene in the gas phase. The morphology and structure of the as-prepared sample were characterized by X-ray diffraction, field-emission scanning electron microscopy, dispersive energy spectrum, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and transmission electron microscopy. The KOH and tetracyanonickelate (II)-fabricated nickel foam showed a good response to low chlorobenzene concentrations ranging from 1 to 50 ppm. The sensor stability test confirmed and the response time of the sensor was approximately 250 s. The developed electrochemical gas flow sensor effectively monitored the exit CB gas during the electrochemical degradation process; the concentration was calculated using a calibration plot. |
