X-ray powder diffraction (XRD) pattern of the products was recorded on a Rigaku (Japan) D/max-?A X-ray diffractometer equipped with graphite monochromatized Cu KR radiation (ì ) 1.54178 ?). The transmission electron microscopy (TEM) images and selected-area electron diffraction (SAED) patterns were captured on a Hitachi model H-800 instrument at an accelerating voltage of 200 kV. High-resolution transmission electron microscopy (HRTEM) images and SAED patterns were obtained on JEOL-2010 transmission electron microscope at an accelerating voltage of 200 kV. The Raman spectrum was recorded with a LABRAM-HR confocal Laser MicroRaman spectrometer with 514.5 nm radiation from an argon laser at room temperature. X-ray photoelectron spectra (XPS) were obtained from an ESCALAB MK II X-ray photoelectron spectrometer by using nonmonochromatized Mg Kα X-ray as the excitation source with an overall energy resolution of 1.0 eV. 展開
