Abstract

To create a gas-sensitive layers of metal oxide sensors used nanopowder sintering of tin dioxide
with catalytic additives. Tin dioxide powder was synthesized by thermal dehydration of the colloidal
particles of tin acids obtained by hydrolysis of the acetate of tin. Catalytic addition of Pd, Pt, Au and CuO
increased sensory response in relation to hydrogen sulfide. The lowest detection limit for hydrogen
sulfide sensor was achieved with the addition of CuO to less than 1 ppm
