FIELD: chemistry.
SUBSTANCE: sensor according to the invention has a non-conducting substrate made from graphite fluoride, which is obtained by fluorinating graphite, on which there a sensitive layer. The sensitive layer is formed by treating the graphite fluoride surface with vapour of a reducing agent. The reducing agent used is hydrazine-hydrate, hydrazine, water or hydrogen peroxide, for example. Operating characteristics of the sensor are restored by blowing with air.
EFFECT: invention enables to make a sensor with high temporary stability and short response time.
