| 摘 要： | The γ-Al2O3 supported CuO samples were studied. XRD results showed that the loading and calcination temperature affected the surface structure. For example， CuO crystallite appeared at the CuO loading of 7% (about 0.82mmol/100m2) on the support. Both CuO crystallite and CuAl2O4 spinel were present when the CuO/γ-Al2O3 sample was calcined at the same temperature (400℃). Microcalorimetric adsorption of CO2 and NH3 revealed that the strength of both the acidity and basicity decreased with the increase of CuO loading for the CuO/γ-Al2O3 sample. The increase of calcination temperature further decreased the basicity while the acidity was not affected.
