The CuO/CeO2 system was investigated as a catalyst for preferential CO oxidation reaction in hydrogen-rich feed (PROX-CO). The catalysts were prepared by deposition-precipitation (DEP) and co-precipitation (COP) methods and the catalytic performance reveals that the preparation method influences the properties of solids prepared, where a direct con...

4.5 nm nanoceria particles are successfully encapsulated into the apoferritin cavity via a dissociation-reconstruction route. The apoferritin coating not only improves the biocompatibility and changes the cellular uptake route of nanoceria, but also manipulates the electron localization at the surface of the nanoparticle thereby ameliorating the RO...
A simple solvothermal method has been used to synthesize novel double-shelled CeO2 hollow spheres (HSs) in a mixed solvent of PEG-400 and H2O. The structure and morphology of the CeO2 HSs were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and nitrogen adsorption-desorption isoth...
The reaction between lanthanum-gallate electrolyte and Ni in the anode often occurs during the co-firing of an anode-supported cell and results in the degradation of cell performance. In this study, a thick-film LSGM (La(0.9)Sr(0.1)Ga(0.8)Mg(0.2)O(3-delta)) electrolyte-supported micro-cell was fabricated and electrochemically tested to see the effe...
Acceptor-doped barium cerate perovskite oxides act as high temperature proton conducting ceramics, which can be utilized in solid oxide fuel cells, hydrogen separation membranes, and other electrochemical devices. One of the major issues in their fabrication is the formation of second phases during sintering of these perovskite oxides. In this work...
CeO2 nano-octahedrons were synthesized with a facile hydrothermal synthesis process where Ce(NO3)(3)center dot 6H(2)O and urea were used as a cerium resource and mineralizer respectively and no surfactant or template was applied. The effects of synthesis parameters such as reaction temperature, reaction time, as well as the dosages of Ce (NO3)(3)ce...
