Mild activation of CeO2-supported gold nanoclusters and insight into the catalytic behavior in CO oxidation.
We report a new activation method and insight into the catalytic behavior of a CeO2-supported, atomically precise Au144(SR)60 nanocluster catalyst (where thiolate -SR = -SCH2CH2Ph) for CO oxidation. An important finding is that the activation of the catalyst is closely related to the production of active oxygen species on CeO2, rather than ligand removal of the Au144(SR)60 clusters. A mild O2 p...

متن کاملCatalytic oxidative dehydrogenation of propane over Mg–V/Mo oxides
Fifteen distinct MgO–V2O5, MgO–MoO3, MgO–V2O5–MoO3, and V2O5–MoO3 compositions were prepared using sol–gel chemistry and their selectivities and conversions for propane oxidative dehydrogenation (ODH) to propylene were measured. The vanadates were more active than the molybdates at lower temperatures; however, the molybdates exhibited higher selectivities at similar conversions. An increase in ...
متن کاملUltrathin Co3O4 nanowires with high catalytic oxidation of CO.
Ultrathin Co(3)O(4) nanostructures with high catalytic oxidation of CO were synthesized by heating cobalt foils under atmospheric conditions. The Co(3)O(4) nanostructures were selectively exposing (111) planes composed of plenty of Co(3+) cations. We observed ultrahigh catalytic oxidation of CO in Co(3)O(4) nanowires with about 3 nm diameter.
متن کاملCatalytic evaluation of promoted CeO2-ZrO2 by transition, alkali, and alkaline-earth metal oxides for diesel soot oxidation.
Series of mixed metal oxides were synthesized by gel-combustion method and their catalytic activities for soot oxidation were investigated. The catalysts were M-Ce-Zr (M = Mn, Cu, Fe, K, Ba, Sr), and xK-20Mn-Ce-Zr (x = 0, 5, 10, 20), they were characterized by XRD, SEM, TPR and BET surface area techniques. The results of soot temperature programmed oxidation (TPO) in an O2 oxidizing atmosphere ...
