Nanocrystalline SnO 2 produced in different ways has been subjected to H 2 S at 100Β°C. The formation of SnS x was deduced from Raman spectra and correlated with the changes in electrical resistance. When the initial resistance of the sample was high, adsorbed SO 4 was observed. The agreement of thes
