SrTi 0.7 Co 0.3 O 3, SrTi 0.7 Cu 0.3 O 3, SrTi 0.7 Co 0.15 Cu 0.15 O 3 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/SrTi 0.7 Co 0.3 O 3 nanocomposite. High conversions were obtained in CO oxidation (90% at 350° C for SrTi 0.7 Co 0.3 O 3). Only CuO/SrTi 0.7 Co 0.3 O 3 was observed to be active in NO reduction (100% at 350° C)

Abstract
SrTi 0.7 Co 0.3 O 3, SrTi 0.7 Cu 0.3 O 3, SrTi 0.7 Co 0.15 Cu 0.15 O 3 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/SrTi 0.7 Co 0.3 O 3 nanocomposite. High conversions were obtained in CO oxidation (90% at 350° C for SrTi 0.7 Co 0.3 O 3). Only CuO/SrTi 0.7 Co 0.3 O 3 was observed to be active in NO reduction (100% at 350° C)File in questo prodotto:
