Application of crystal fiber red phosphorus in gas detection

The invention belongs to the technical field of sensors, and discloses application of crystal fiber red phosphorus in gas detection, and the crystal fiber red phosphorus is used for gas detection through the following steps: step 1, uniformly dispersing the crystal fiber red phosphorus in a solvent medium, grinding into mixed slurry, then uniformly coating a ceramic tube with the mixed slurry, and drying to obtain the crystal fiber red phosphorus; and drying the ceramic tube coated with the mixed slurry to cure the mixed slurry to obtain the gas sensor. 2, after the obtained gas sensor is in contact with gas to be detected, the gas sensor in contact with the gas to be detected is detected through a Raman/infrared method, and detection of the gas to be detected is achieved. The crystal fiber red phosphorus is used for detecting gas, rapid response to ammonia gas under the room temperature condition can be achieved, the detection method is easy to operate, safe and efficient, and a way is laid for ammonia gas d
