Tracking in Detail the Synthesis of Cadmium Oxide from a Hydroxyl Gel Using Combinations of in Situ X-ray Absorption Fine Structure Spectroscopy, X-ray Diffraction, and Small-Angle X-ray Scattering

摘要: The synthesis of cadmium oxide from a gel hydroxide has been followed in situ using unique combinations X-ray diffraction (XRD), absorption fine structure (XAFS) spectroscopy, and small-angle scattering (SAXS). XRD XAFS enable the crystallography, particle size, local to be quantified as hydroxyl converts into around 182 °C. SAXS measures evolving microstructure, with growing dendritically fractal geometry, initially rough nanoparticles. Major growth densification takes place between 325 550 implications for characterizing precipitation nanoparticles zeolitic hosts are considered.
