Highly sensitive so2 fittings

Highly sensitive so2 fittings

In this work, we report the development of a highly sensitive SO 2 photoacoustic sensor for the application of sf6 decomposition detection in an electric power system. A small-sized UV-band diode-pumped solid-state laser (DPSSL) emitting at 303.6 nm with an output power of 5 mW was employed, whose wavelength corresponds to a strong interference-free electronic spectrum of SO 2 .

  • Highly sensitive and selective SO2 MOF sensor: the

    The fabricated sensor exhibits significant detection sensitivity to SO 2 at concentrations down to 75 ppb, with the lower detection limit estimated to be around 5 ppb. The MFM-300 MOF sensor demonstrates highly desirable detection selectivity towards SO 2vs. CH 4, CO 2, NO 2 and H 2, as well as an outstanding SO 2 sensing stability.

  • SO2-Induced Selectivity Change in CO2 Electroreduction

    In the cases of Ag and Sn, the effect of SO 2 impurity was reversible and the catalytic activities of both catalysts were recovered. On the contrary, a shift in selectivity toward formate accompanied by a suppression of multicarbon (C 2+) products was observed on Cu catalyst, demonstrating that Cu is highly sensitive to SO 2 impurity.Cited by: 21

  • Ultrasensitive SO2 sensor for sub-ppm detection using Cu

    Dec 01, 2020Interestingly, the Cu-SnO 2 NSAs sensors present a highly sensitive detection ability toward SO 2 in a dry environment, and the detect concentration can be as low as 0.1 ppm. In addition, the SO 2 sensing behavior of Cu-SnO 2 NSAs can be greatly affected by test conditions (environment humidity and operation temperature), and the corresponding SO 2 sensing mechanism is proposed.
