Sorption processes on the surface of metal oxide nanowire and determination of low concentration of hydrogen sulfide and acetone
SnO <sub>2</sub>-sensors were obtained by two different methods. The first one is based on platinum contacts deposition to individual nanowire by FIB. Another one type of sensor was obtained by sol-gel process, based on calcination of SnO <sub>2</sub>-nanopowder. Both types of sensors were able to detect 1 ppm of hydrogen sulfide and acetone. Sensor responses were demonstrate high reproducibility. Sensor, based on SnO <sub>2</sub> individual nanowire, was more sensitive and stable than one, obtained by sol-gel method.
