摘要：

This study used synchrotron-based X-ray absorption spectroscopy (XAS) to investigate the electronic properties and coordination environment of zinc in the Zn-doped Al2O3 after thermal treatment at 500 and 1100 degrees C for 2 h. Zn XANES spectra show that there is a main peak at the edge between 9665 and 9670 eV After 500 degrees C thermal treatment, zinc was in the form of ZnO. However, there is nearly 10 eV peak separation in the white band area after 1100 degrees C thermal treatment suggesting the existence of chemical reaction product between ZnO and Al2O3.
