Abstract

The oxygen chemisorption on nanocrystalline SnO2 at temperature range between 100 and 450 °C was studied with differential thermal analysis (DTA) and electrical conductivity measurement. The O2-, O-, and O2- ionosorptions were observed and could be distinguished from each other only on nanocrystalline SnO2 with grain size less than 5 nm. Assuming steady-state adsorption, the heats of adsorption for O2- and O- (or O2-) on nanocrystalline SnO2 are 1.09 and 1.50 eV respectively from the results of DTA.
