摘要：

Au was loaded (1.5 wt.%) on the supports (ZnO, Al(2)O(3) and MgO) by a colloidal deposition method. For a range of low temperatures (50-300 degrees C), the catalytic activity of Au/ZnO was much greater than that of Au/Al(2)O(3) and Au/MgO. In particular, for the Au/ZnO, the benzene conversion exceeded 80% at 150 degrees C. The results of catalyst characterization suggested that the high catalytic activity of the Au/ZnO might be attributed to the effects of strong metal-oxide interaction which is possibly originated from the small lattice parameter difference between Au {111} and ZnO {101} lattice planes.
