Bimetallic Ru–Pd supported on CeO2 for the catalytic partial oxidation of methane into syngas
نویسندگان
چکیده
A series of monometallic Ru, Pd, and bimetallic Ru–Pd catalysts loaded on CeO2 support have been prepared via mechanochemical conventional incipient wetness impregnation methods used in the partial oxidation methane (POM) to obtain synthesis gas (H2 CO). The influence preparation method, order addition metals, Ru:Pd metal ratio, milling energy time for samples by evaluated between 300 600 °C. results revealed that Ru–Pd/CeO2 outperform Ru–CeO2 Pd–CeO2 POM, both terms catalytic activity stability. Additionally, ball produced syngas at a much lower temperature compared impregnation. Raman spectroscopy, programmed reduction (H2–TPR), X–ray photoelectron spectroscopy (XPS) high–resolution transmission electron microscopy (HRTEM) characterize before after reaction.

Recent Developments in the Partial Oxidation of Methane to Syngas
Natural gas is catalytically converted into several bulk chemicals such as ammonia, methanol, dimethyl ether, and synthetic liquid fuels by Fischer-Tropsch synthesis and similar processes. The main step in the conversion of natural gas to these products is the production of synthesis gas with the desired composition ranging from H2/CO = 3:1 used for the production of ammonia to the 1:1 mixture ...
متن کاملMild 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 partial oxidation of methane to synthesis gas over Ni–CeO2
The partial oxidation of methane to syngas was studied in this work over Ni-containing ceria catalysts with nickel content of 5, 10 and 20 at.% at atmospheric pressure. All catalysts, in the as prepared state, showed similar activity and CO selectivity at T ≥ 550◦C. Catalyst pre-reduction was not required. Reaction mixtures were dilute, containing 3 mol% CH4 and 1.5 mol% O2. Methane conversion ...
متن کاملComputational Design of a CeO2‐Supported Pd-Based Bimetallic Nanorod for CO Oxidation
Engineering a bimetallic system with complementary chemical properties can be an effective way of tuning catalytic activity. In this work, CO oxidation on CeO2(111)supported Pd-based bimetallic nanorods was investigated using density functional theory calculations corrected by on-site Coulomb interactions. We studied a series of CeO2(111)supported Pd-based bimetallic nanorods (Pd−X, where X = A...
متن کاملSynthesis and characterization of Pt3Co bimetallic nanoparticles supported on MWCNT as an electrocatalyst for methanol oxidation
The impregnation method was used to synthesize Pt and Pt3Co supported on MWCNTs applying NaBH4 as the reducing agent. The structure, morphology, and chemical composition of the electrocatalysts were characterized through SEM, XRD, and EDX. X-ray diffraction showed a good crystallinity of the supported Pt nanoparticles on the composites and showed the formation of Pt3<...
