Mesoporous CuO/SnO2 adsorption enhanced sensor, and detection method

摘要: The invention relates to a mesoporous CuO/SnO2 adsorption enhanced sensor, and detection method. According the microsphere-type directly-heated type sensor is fixed on pedestal, composed of platinum wire, wire coil, sensitive material; coil penetrated by wire; are packaged with material microsphere structure; high temperature heating circuit pulse circuit, first current source, coil; low second used for outputting signals, connected alternatively. capable increasing sensitivity absorbing gas. possesses two operating temperatures because driving, so that it beneficial gas, gas extremely concentration increased.
