Synthesis and characterization of molybdenum catalysts supported on γ-Al2O3-CeO2 composite oxides
The physical and chemical properties of a catalyst play a vital role in various industrial applications. Molybdenum catalysts supported on γ-Al2O3 and γ-Al2O3-CeO2 mixed oxides with varying loading of CeO2 (5, 10, 15, 20 wt % with respect to γ-Al2O3) were prepared by wet impregnation method. The phy...
