Structure of Copper-Based Aerogel on XRD Refinement

The crystal structures of copper-based aerogels calcined with different temperatures have been analyzed by powder diffraction data. Compared with the three compounds' XRD patterns of experiment and simulation, the R-WP is in reasonable range, 8.15%, 10.08%, and 4.91%, respectively. As temperature increases, the compounds show different crystal structures. At 200 degrees C, crystal system of compound 1 is monoclinic; and then crystal system of compound 2 is orthorhombic at 300 degrees C; when compound 3 was calcined at 400 degrees C, the crystal system is triclinic.
