Abstract
We synthesized hexagonal phase Pr(OH)(3) nanorods by a hydrothermal method and obtained cubic phase Pr6O11 by post-thermal annealing at above 550 degrees C. Pr(OH)(3) nanorod growth was found to occur in the [001] direction. Upon thermal annealing, the oxidation state of Pr(III) was changed to Pr(III, IV). The physicochemical properties were fully examined by scanning electron microscopy (SEM), high resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD) crystallography, UV-Visible-NIR absorption, differential scanning calorimetry/thermogravimetric analysis (DSC/TGA), X-ray photoelectron spectroscopy (XPS), and temperature-programmed reduction (TPR) and CO oxidation activity tests.
