(Trans)acetalization Reactions for the Synthesis of Oligomeric Oxymethylene Dialkyl Ethers Catalyzed by Zeolite BEA25

Oligomeric oxymethylene dimethyl ethers (DMEs; OMDMEn) are acetals of the type CH3O(CH2O)nCH3 with a high oxygen content and without carbon–carbon bonds in the molecular structure. Therefore, formation of soot and NOx emissions is largely …

Properties of Isolated and TiO2(110) Supported Pt13 Clusters: A Theoretical Study

Metallic subnanoparticles deposited over supports such as TiO2 play an important role for the design of model catalysts for heterogeneous catalysis applications. In this work we study the structure and energetic of Pt13 clusters deposited on …

Gold Stabilized with Iridium on Ceria–Niobia Catalyst: Activity and Stability for CO Oxidation

Monometallic gold and iridium, and bimetallic gold–iridium on ceria–niobia (Nb2O5–CeO2) catalysts were synthesized by deposition–precipitation with urea. Ceria–niobia support, synthesized by co-precipitation, presented a higher reducibility and a …
