Intergrowth effect of CuO–γ-Al2O3 mixed oxides

Abstract

The intergrowth of mixed oxides CuO and γ-Al2O3 have strong mutual interactions, and their microstructures are modified. There are alternating positive and negative charges in the γ-Al2O3 crystallite. Simultaneously, one kind of Cu–O bond length becomes longer. These two effects result in the intergrowth mixed oxides having a higher CO catalytic oxidation performance.
