METHOD FOR PRODUCING MATERIAL GAS SENSOR selective detection of H2S and its derivatives

摘要

1. A method of manufacturing a gas sensor material for selective detection of HS and of its derivatives in the air, comprising forming whiskers n-type conductivity on the basis of SnO, ZnO, InO, impregnation of these crystals salt solutions Cu, Ni, Co, followed by annealing prior to the formation conductivity oxides p-type CuO, NiO, CoOi form a p-n geterokontaktov.2. A method according to claim 1, characterized in that the resulting material is further deposited on the insulating substrate made of polycrystalline alumina with platinum measuring electrodes on the front side and the platinum thin-film heater on the back storone.3. A method according to claim 1, characterized in that the resultant material is applied in paste form with a binder, which is used as a solution in an alcohol-terpineol, whereupon heating the paste at a temperature of 450 ° C for 6 hours to remove the binder.
