Ni/CeO2eMgO catalysts on powder form and supported on stainless steel plates were prepared, characterized and tested towards hydrogen generation via the steam reforming reaction of ethanol. The structured catalyst was prepared by the dip-coating technique. The coatings obtained over the stainless steel plates were homogeneous and retained their integrity after the reaction experiences. The samples were characterized by SEM, TEM, XRD, ICP-AES, TPR, OSC and N2 adsorptionedesorption measurements. Catalysts presented very good stability under reaction conditions for 16 h on-stream, without showing a significantvariation in the activity or product distribution. The structured catalysts presented similar activities and selectivities respect to those of the powder, whereby the deposition method did not modify the catalytic properties of the particulate material. The presence of the AISI 430 stainless steel substrate also had not a significant influence on the performance of the deposited material.
