Gold supported on ceria is a well known oxidation catalyst. The implementation of catalysts in industry requires the use of suitable supports, such as ceramic honeycomb monoliths, due to high pressure drop of powder catalysts at high flow rates. The aim of this work was to propose the methods for gold introduction during the preparation of monolithic catalysts and to investigate their effect on catalyst properties. Washcoating with ready-made gold/ceria-zirconia catalyst and deposition of gold onto ceria-zirconia washcoat were compared and the catalytic performance in ethanol oxidation was correlated with physicochemical properties of the catalysts.
