We report a facile hydrothermal synthesis in base solution for shape/size-controlled ceria (CeO2) nanocrystals and CeO2-ZrO2 solid solution. CeO2 nanocrystals in the shape of nanorods, nanotubes, or nanocubes with reactive {110} and {200} faces can be produced using this hydrothermal method. We found that hydrothermal reaction temperature is a critical parameter to control the shape and size of ceria nanocrystals. Above 210 °C, high resolution transmission electron microscopy studies revealed that the CeO2 nanocubes expose predominant {200} crystal planes. Microscopic investigation showed that the CeO2-ZrO2 solid solutions synthesized using this method had high crystallinity, and compositional homogeneity, and improved low-temperature reducibility.

Initial Ph

ABSTRACTThe hydrothermal reaction of vanadium pentoxide with methylamine leads to a series of new layered vanadium oxides by using different acids to adjust the initial pH. The structure of these layered vanadium oxides was established by X-ray single crystal and powder diffraction. The new phases were also characterized by TGA and FTIR. The oxidation state of vanadium was determined. These materials are expected to exhibit catalytic activity and may be of interest as cathode materials for secondary lithium batteries.

Nb5+-doped SrTiO3(STO) particles were synthesized by a simple hydrothermal reaction at 150 °C for 4h. It was found that the main diffraction peaks of Nb5+-doped STO samples with different dosage of dopants shifted gradually to low angles, indicating the little lattice parameter expansions which result from the partial substitution of Ti4+(0.061 nm) by Nb5+(0.064 nm) in perovskite structure. From the lattice parameters, the max Nb5+dopant concentration is about 2 mol%, and the particles obtained were 200 nm-sized and monodispersed.
