A series of nanosized perovskite oxides, LaCoO3 and La1-xBxCoO3 (x=0.1; B: Sr, Ag), was synthesized by citrate method. The samples were characterized by XRD, IR and SEM. The XRD results show that all samples have principal phase with rhombohedra perovskite structure and particles size of 30-50 nm. The catalytic performance of these nanoperovskites has been evaluated by the total combustion of 1000 ppm of toluene in air. The result obtained shows the highest activity for the sample La0.9Ag0.1CoO3. The last one seems to be related with the highest quantity of oxygen released as showed by oxygen temperature program desorption results (O2-TPD). [DOI: 10.1380/ejssnt.2011.486]
