A fast response cataluminescence ether gas sensor based on GO/Mo(2)TiC(2)T(x) at low working temperature

A cataluminescence (CTL) ether gas sensor based on GO/Mo(2)TiC(2)T(x) composite was developed. The sensor has high selectivity and sensitivity to ether with the response and recovery times of 2 and 8 s, respectively. The optimal operating temperature (155 °C) is low compare with common sensors. Unde...

Sumario:A cataluminescence (CTL) ether gas sensor based on GO/Mo(2)TiC(2)T(x) composite was developed. The sensor has high selectivity and sensitivity to ether with the response and recovery times of 2 and 8 s, respectively. The optimal operating temperature (155 °C) is low compare with common sensors. Under optimal conditions, the linear range of the concentrations of ether is 9.5–950 ppm; CTL signal intensity and ether concentration show a good linear relationship (r = 0.9952); and the detection limit is 0.64 ppm. Furthermore, no response to anything other than acetone after repeatedly tested 10 kinds of common volatile organic compounds, which shows that the sensor has a good selectivity. In addition, the developed sensor has a long life.
