Annotation	The aim of this work was to study the effect of gold loading on ceria-zirconia support, and to investigate the influence of VOC type on the catalytic performance. A key part of the work reveals a less known role of the large gold agglomerates in the oxidation process. Ce0.5Zr0.5O2 was impregnated with a constant volume of aqueous solution of gold(III) acetate. The concentration of the solution varied in order to obtain different gold loadings. The samples were calcined 5 h at 500 °C to obtain highly stabile and robust catalysts. H2-TPR and OSC measurements confirmed the positive effect of gold loading on reducibility and oxygen mobility.
