Popis:	Chemisorption of SO2 and O2 at Pt-modified SnO2 is studied by using the vacuum static method, with simultaneous recording of electrical conductivity, over the 22 to 300°C temperature range. The SnO2 surface modification results in the increasing of SO2 adsorption and weakening of the gas-surface bonding. The chemisorption enhances the samples’ electrical conductivity. The surface pretreatment with oxygen leads to the decreasing of the successive SO2 chemisorption.
