This paper reports the results of a study on the preparation of structured catalysts by chemical conversion coating. The ceria coating was realized by reacting suitably pre-treated aluminum structures with an oxidizing solution of cerium chloride; the obtained samples were characterized by means of several analytical techniques to evaluate the coverage percentage, the surface morphology and the surface chemical structure. A preliminary screening on the reactivity of the system, to find the

The obtained catalyst was loaded with platinum as active phase and tested in water gas shift reaction for hydrogen production.
