✦ Synopsis
These materials and their methods of preparation are described in a previous paper [13].
X-ray Diffraction Studies: As-prepared and calcined samples were characterized using a Rigaku Rotating Anode Goniometer. Details are provided in a previous paper [13]. Low-angle XRD scans were also obtained from 2h = 4±10 using a scan rate of 0.25 min ±1 in 0.01 increments. Jade (Version 3.1 from Materials Data, Inc., Livermore, CA) was used to identify the crystallographic phases and relative phase compositions. CrystalMaker and CrystalDiffract (Versions 6 and 4, respectively, from CrystalMaker, Bicester, UK) were used to model the new phase and to simulate the XRD pattern.
Diffuse-reflectance Fourier-transform IR spectra (DRIFTS), specific surface analyses (Brunauer±Emmett±Teller analysis), and scanning electron microscopy data were recorded as described elsewhere [13].
Transmission Electron Microscopy: Micrographs were obtained using a JEOL 2100 XL. Samples were prepared using a carbon-coated copper TEM grid (300 mesh). The powder was dispersed in distilled water using an ultrasonic horn as before [13], and then a drop of the dispersed powder/water mixture was deposited on the grid. The grid was then dried for 4 h at 80 C. The JEOL 2100 XL was used with an accelerating voltage of 200 kV.
