摘要: Abstract The addition of alkali (earth) metal oxides (MO x , with M = Li, Rb, Mg, or Ba) is beneficial for the performance Au/Al 2 O 3 catalysts in total oxidation propene (C H 6 ). effect MO additives on microstructure and nature catalyst was investigated by X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), surface area (BET), diffuse reflectance ultraviolet visible spectroscopy (DR-UV/vis). It found that induces a decrease size gold particles stabilizes them against sintering. In turn, direct dependence catalytic found. role structural promoter not chemical promoter.
