In this paper, we presented a
carbon tetrachloride
gas sensor
with strong cataluminescence response based on Ag2Se nanomaterial, which was synthesized via the electrodeposition on the surface of Al foil by directly using a non-aqueous
dimethyl sulfoxide
(DMSO) solution with CH3COOAg and SeCl4. The deposited Ag2Se material was characterized by
scanning electron microscopy
(SEM), X-ray diffraction (XRD) and X-ray
photoelectron spectroscopy
(XPS). Then, the prepared Ag2Se material along with the Al foil substrate was employed to design the
carbon tetrachloride
gas sensor. Under the optimized conditions, the present
gas sensor
exhibited a broad linear range of 0.9–228μgmL−1, with a
limit of detection
of 0.3μgmL−1 (S/N=3). The proposed
gas sensor
showed good characteristics with high selectivity, fast response and long lifetime.
