Abstract. A tailor-made encapsulated catalyst with a H–B zeolite shell has been directly synthesized over Co/Al2O3 pellets to form a core–shell structure without pinholes and cracks by a hydrothermal synthesis method. Pretreatment of the Co/Al2O3 pellets with reflux of hot TEAOH solution can clean and corrode the pellet surface due to its strong basicity, and can enlarge the mean pore s…
Abstract. Ag–TiO2 nanostructured thin films with silver volume fraction of 0–40.0% have been deposited on silicon and quartz substrates by RF magnetron sputtering. Their crystal texture, surface topography, and hydrophilicity have been characterized by X-ray diffractometer, transmission electron microscope, and water contact angle apparatus. The relation of hydrophilic property and silv…
Abstract. A series of nanostructured Pd-doped mixed oxides MOx-CeO2 (M = Mn, Fe, Co, Ni, Cu), with uniform mesoporous structure and large surface area exceeding 115 m2 g-1, were synthesized in one step by a surfactant-assisted co-precipitation. Their catalytic performance was investigated using total oxidation of CO and C3H8 as the model reactions. The results show that, a synergism exists…
Abstract Nanorods and nanoparticles of CeO2 were successfully synthesized and used as support of Pd/CeO2 catalysts. It is found that the nanorods show obvious advantages as the support, compared with the nanoparticles. Low efficiency in the formation of reduced Pd, and partial encapsulation of Pd species account for the poor activity of Pd supported on CeO2 nanoparticles. On the contrary, a …
