Abstract EN
In this paper, g-C3N4-WO3 composite materials were prepared by hydrothermal processing.
The composites were characterized by means of X-ray powder diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), and N2 adsorption-desorption, respectively.
The gas sensing properties of the composites were investigated.
The results indicated that the addition of appropriate amount of g-C3N4 to WO3 could improve the response and selectivity to acetone.
The sensor based on 2 wt% g-C3N4-WO3 composite showed the best gas sensing performances.
When operating at optimum temperature of 310°C, the responses to 1000 ppm and 0.5 ppm acetone were 58.2 and 1.6, respectively, and the ratio of the S1000 ppm acetone to S1000 ppm ethanol reached 3.7.
