Catalytic Behaviour of Flame-Made CuO-CeO2 Nanocatalysts in Efficient CO Oxidation

CuO Nanorods-Decorated Reduced Graphene Oxide Nanocatalysts for Catalytic Oxidation of CO

Developing an efficient non-noble catalyst for CO oxidation with high catalytic activity remains a challenge for practical applications. In this work, CuO nanorods decorated reduced graphene oxide (RGO) nanocatalysts were prepared via a facile one-step hydrothermal method. The structure and morphology of the as-prepared samples were characterized by XRD, Raman spectroscopy, SEM, TEM, and X-ray ...

Catalytic Decomposition of Ammonia over Bimetallic CuO/CeO2 Nanoparticle Catalyst

The oxidation of ammonia to nitrogen by selective catalytic oxidation (NH3-SCO) over a bimetallic CuO/CeO2 nanoparticle catalyst at temperatures between 423 and 673K. A bimetallic CuO/CeO2 nanoparticle catalyst was prepared by co-precipitation method at molar ratio of 6:4. This study also considers how the concentration of influent NH3 (C0 = 800 ppm), the space velocity (GHSV = 92000/hr), the r...

The Preparation and Catalytic Performance of Nanoporous CuO/CeO2 Composites

Nanoporous CuO/CeO2 ribbons are successfully prepared through dealloying melt-spun Al80−xCu20Cex (x = 0.5, 1, 2, 3, at%) alloy in a 5 wt% NaOH aqueous solution, followed by calcining in air. The samples are characterized by XRD, SEM, EDS, HRTEM, Raman and gas chromatograph. For the dealloyed melt-spun Al80−xCu20Cex (x = 0.5, 1, 2, 3, at%) alloy, the XRD results indicate that Cu and Cu2O are for...

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...
