  • Detection of CF4 Gas Using a Nanomaterial-Based Gas Sensor

    Aug 26, 2019 · Because CF 4 is hard to be removed by using a molecular sieve or absorbent, the decomposition product accumulates in a long time and can be used for GIS diagnosis. Three kinds of semiconducting nanomaterial, carbon nanotube, SnO 2 nanoparticle, ZnO nanowires, were integrated on a microelectrode by dielectrophoresis respectively to fabricate a gas sensor.
