摘要：
Nanocrystalline SnO2 produced in different ways has been subjected to H2S at 100 degrees C. The formation of SnSx was deduced from Raman spectra and correlated with the changes in electrical resistance, When the initial resistance of the sample was high, adsorbed SO4 was observed. The agreement of these results with available thermodynamic data and the actual theory of SnO2 sensitivity to H2S is discussed. (C) 1999 Academic Press.
