| Abstract: | The surface electronic structure of the binary metal oxide ZrO2/SiO2 was studied by means of XPS and the decrete variational (DV) Xα cluster model calculation. The results show that when ZrO2, was supported on SiO2, the SiO bond of SiO2, neighboring ZrO4, became stronger and that the Brönsted acid site H which is located on the SiO4 unit exhibits stronger acidity. |
