Article Snippet: High-angle annular dark-field scanning TEM (HADDF-STEM) was conducted on JEOL NEOARM 200 F. High-resolution TEM (HRTEM) images were obtained using a Jem-2100F and energy spectrum was Oxford X-MAN 65 T. XAFS characterization: The XAFS spectra are obtained at 1W1B station in BSRF (Beijing Synchrotron Radiation Facility, P. R. China) operated at 2.5 GeV with a maximum current of 250 mA.
