Cu0.15Ce0.85O2-y Mixed Oxide Catalyst Prepared by Co-precipitation Synthesis
The use of CeO2 and CeO2-containing materials as a component of heterogeneous industrial catalysts or as a support for transition metals is based on superior chemical and physical stability, high oxygen mobility and high oxygen vacancy concentrations, which are characteristic for the fluorite-type oxides (economically and technologically most important application is the use of ceria in the thr...
متن کاملStructure and Magnetic Properties of Oxide Nanoparticles of Fe-Co-Ni Synthesized by Co-Precipitation Method
Oxide nanoparticles of Fe-Co-Ni were prepared in six different compositions by co-precipitation method. The as-synthesized nanoparticles were characterized by X-Ray Diffraction (XRD), Field Emission Scanning Electron microscope (FESEM), Fourier Transform Infrared (FT-IR) and Vibrating Sample Magnetometer (VSM). It was found that the nanoparticles had mean crystalline size of 30-55 nm and spher...
متن کاملSintering of Al2O3–Ceo2nanopowder Prepared by Co-Precipitation Method
In the present work, Al2O3-CeO2 composite nanopowders were synthesized via co-precipitation method. The sinterability of the synthesized powders was investigated. The results showed that the transformation of transition phases of alumina to α-Al2O3 takes place at 1200 °C. TEM images showed that the powders was composed of nanoparticles in the range of 30−70 nm. The densification of composites s...
متن کاملEnhancing selective catalytic reduction of NOx with alternative reactants/promoters
The hydrocarbon-selective catalytic reduction (HC-SCR) activity of an Ag/Al2O3 catalyst was investigated. The function on catalytic NOx reduction of different fuel properties using alternative reactants such as gas-to-liquid (GTL) and butanol was studied. This work proves that such improvements are due to the high reactivity, polarity and diffusivity of butanol within the catalyst enhancing NOx...
متن کاملThe Selective Catalytic Reduction of NOx with NH3 over Titania Supported Rhenium Oxide Catalysts
Titania supported vanadium oxide catalysts have been demonstrated to be very efficient catalysts for the selective reduction of NOx with NH3 and have found widespread industrial application for the control of NOx emissions from stationary sources (1). Characterization studies have demonstrated that supported vanadium oxide catalysts consist of a two-dimensional metal oxide overlayer on the oxid...
