| Popis: | The control of oxide nanoparticle size and shape is of great importance to tune their physical and chemical properties. As a consequence, routine methods are required to determine the nanoparticle morphology. Since diffraction patterns strongly depend on both size and shape, X-ray powder diffraction (XRD) is widely used to determine the particle morphology. Herein, an accurate approach is proposed based on the simulation of morphology-dependent diffraction patterns using the Debye formula and on the comparison of these calculated patterns to the experimental ones. The most representative particle morphology is also obtained. This methodology has been first validated on a simple model system of MgO cubic and octahedral nanoparticles. It has been then applied to three different morphologies of boehmite AlOOH samples, obtained by varying the synthesis pH value. The method is characterized in terms of sensitivity, and extensive comparisons with transmission electron microscopy (TEM) results are also performed... |
