Manganese oxide-loaded and -doped ceria as well as the corresponding barium-modified oxide catalysts were prepared for soot oxidation in the presence of NO(x), and were characterized by using X-ray diffraction, Brunauer-Emmett-Teller and NO temperature-programmed oxidation measurements. The activity of catalyst depended strongly on the NO2 production capacity, and the importance of surface nitr...

CeO2-based catalysts as cathodes in solid oxide electrolysis cells (SOECs) have great potential for improving the storage of renewable electricity form H2 via water-splitting reaction (WSR). A key challenge to promote WSR on CeO2 is facilitating decomposition stable surface hydroxides H2. Here, we use density functional theory investigate effect Bi- and Pr- doping CeO2(1 1 1). We find that dopa...

Nanocrystalline ceria has been considered as support for carbon monoxide preferentially oxidation. In this study ceria was prepared by precipitation method and the effects of preparation conditions, such as pH of solution (8-10), aging time (1-12 hr), drying temperature (80-120 °C), calcination time (2-6 hr) and temperature (400-600 °C) were investigated on ceria synthesized powders properties....
