The scope of this study was to investigate the effect of SnO2addition on the structure and catalytic performance of Co3O4for N2O decomposition. SnO2-Co3O4exhibits much better catalytic activity in the absence or presence of water vapor than Co3O4. Spectroscopic characterization of SnO2-Co3O4showed that this solid possesses higher degree of Co dispersion, smaller Co3O4particles and larger SBETdue to the addition of SnO2. In addition, an interaction between Sn and Co oxides formed at the SnO2/Co3O4interface promotes the electron donation ability of Co2+and facilitates desorption of surface oxygen species, which might be considered as an important factor that contributes to the excellent catalytic performance of SnO2-Co3O4for N2O decomposition.
