英文摘要In this study, hierarchical porous structured CeO2/Al2O3 monolith was prepared through the combination of solgel and heating-drying-calcination methods. Subsequently, the Au-CeO2/Al2O3 monoliths of different Au loadings were prepared by the deposition-precipitation method. When the Au-3.2%-CeO2/Al2O3 monolith was used for low- temperature CO oxidation, compared with Au-3.2%-CeO2/Al2O3 powder particles, excellent activity (temperature of 34 degrees C for complete conversion) and stability (up to 100 h) for the CO oxidation were achieved. Such an excellent performance was attributed to the unique hierarchical porous structure of monolith, the good oxygen storage capacity of CeO2, as well as the excellent CO adsorption and catalytic properties of the monodisperse Au nanoparticles.
