SrTi0.7Co0.3O3, SrTi0.7Cu0.3O3, SrTi0.7Co0.15Cu0.15O3 were prepared by the "citrate route" and characterized (XRD, XPS, SEM, TPR). Their reactivity with respect to CO oxidation and NO reduction was investigated and compared with that of CuO/SrTi0.7Co0.3O3 nanocomposite. High conversions were obtained in CO oxidation (90 % at 350 A degrees C for SrTi0.7Co0.3O3). Only CuO/SrTi0.7Co0.3O3 was observed to be active in NO reduction (100 % at 350 degrees C).

Abstract
SrTi0.7Co0.3O3, SrTi0.7Cu0.3O3, SrTi0.7Co0.15Cu0.15O3 were prepared by the "citrate route" and characterized (XRD, XPS, SEM, TPR). Their reactivity with respect to CO oxidation and NO reduction was investigated and compared with that of CuO/SrTi0.7Co0.3O3 nanocomposite. High conversions were obtained in CO oxidation (90 % at 350 A degrees C for SrTi0.7Co0.3O3). Only CuO/SrTi0.7Co0.3O3 was observed to be active in NO reduction (100 % at 350 degrees C).File in questo prodotto:
