Abstract

 In this study, bulk LaCoO3 was prepared by the citrate method, and supported ones by impregnating silica and alumina with a solution of cobalt and lanthanum nitrates. Different promoters of ceria, zirconia and lanthana were used to inhibit the interaction of the perovskite and the support. The performance of the catalysts was examined from 100 to 750 oC in presence of a simulated automobile exhaust gas. The bulk LaCoO3 converts CO at temperatures less than 300 oC, while it converts C2H6 at about 700 oC. The complete conversion of both CO and C2H6 occurs at temperatures higher than 700 oC on supported catalysts. The XRD spectra of the catalysts show that there is a strong interaction of the perovskite and the support. Ceria as one of the promoters used, shows the best results for reduction of the interactions.
