Dry citrate-precursor synthesized nanocrystalline cobalt oxide as highly acti…
Abstract. A set of nanocrystalline cobalt oxide (Co3O4)-based catalysts have been prepared by means of an innovative soft reactive grinding (SRG) procedure. The catalysts exhibited excellent activities and high stabilities for propane catalytic combustion. Complete conversion has been achieved at reaction temperatures as low as 240 ◦C. Comparing with the highly active Co3O4 catalysts in t…

Effect of pretreatment atmosphere on CO oxidation over a-Mn2O3 supported gold…
Abstract. The microstructural properties of Au/a-Mn2O3 catalysts moderately pretreated under different atmospheres, i.e., O2, He and H2, in relation to their activities and stabilities on CO oxidation were investigated. The highest initial activity was obtained for the He-pretreated catalyst, which, however, suffered the most severe deactivation with time on stream. Pretreatment with O2 res…

Abstract. Cu/SiO2 catalysts prepared by the ammonia-evaporation (AE) method have been systematically characterized focusing on the effect of the AE temperature during catalyst preparation. It is found that the texture, composition, and structure of the calcined and reduced Cu/SiO2 catalysts were profoundly affected by the AE temperature. Based on characterizations and previous findings, the…

Dehydrogenation of propane over spinel-type gallia–alumina solid solution c…
Abstract. Dehydrogenation of propane to propylene in the presence or absence of carbon dioxide was performed over a series of mixed GaxAl10−xO15 oxides (with x varying from 0 to 10) synthesized through an alcoholic coprecipitation pathway. Among the various compositions of GaxAl10−xO15, the maximum activity was observed for x = 8. Whereas the same tendency was observed for the specific …

Gold nanoparticles supported on manganese oxides for low-temperature CO oxida…
Abstract. A series of gold catalysts deposited on various single-phase manganese oxides (MnOx, including MnO2, Mn2O3 and Mn3O4) were studied in relation to their performance in the low-temperature oxidation of CO. Gold was deposited onto the MnOx support by deposition–precipitation with urea (DP urea). The activity of the Au/MnOx catalysts for CO oxidation strongly depends on the nature o…

Preparation of Cu/SBA-15 catalysts by different methods for the hydrogenolysi…
Abstract. Mesoporous siliceous SBA-15-supported Cu catalysts have been prepared by different methods and systematically characterized. The results revealed that the incipient wetness impregnation (IWI)method gives poor dispersion of copper species, whereas much better dispersion is found in catalysts prepared by the deposition precipitation (DP), grafting, and homogeneous deposition precipi…

Abstract Ce-promoted Ru/SBA-15 catalysts were prepared by a ‘‘two solvents’’ impregnation method. In liquidphase hydrogenation of benzene, the Ce-promoted Ru/SBA-15 catalysts exhibited superior catalytic performance to the un-promoted catalyst. The optimum bulk Ce/Ru molar ratio was determined to be 0.25, at which a cyclohexene yield of 53.8% was obtained. Based on characterizations…

Mesostructured CeO2 as an Effective Catalyst for Styrene Synthesis by Oxidati…
Abstract A new type of mesostructured ceria material was synthesized via template-assisted precipitation method and tested for the oxidative dehydrogenation (ODH) of ethylbenzene to styrene by molecular oxygen. The effect of calcination temperature on the catalytic performances of the ceria catalysts has been investigated. Among the catalysts tested, the CeO2-450 sample derived by calcinati…
