Аннотация:Results of investigations aimed at creating a material possessing selective sensitivity to gaseous hydrogen sulfide are presented. Polycrystalline films of doped tin dioxide were obtained by pyrolysis of an aerosol of appropriate organometallic compounds. The effect of copper and nickel oxides on the electrical properties, actual structure, and composition of polycrystalline tin dioxide films was studied. The influence of trace amounts of gaseous H2S on the electrical conductivity of the films was analyzed in detail.
