Ni(7.5 wt.%)/CeO 2 and Ni(7.5 wt.%)-Rh(0.5 wt.%)/CeO 2 powders (previously prepared by solution com-bustion synthesis) were washcoated on cordierite monolith and alumina open-cell foam by means of support dip-coating into acid-free catalyst dispersion. Catalytic performances toward the steam reform-ing (SR) and the oxy-steam reforming (OSR) of biogas were investigated and compared at different temperatures (700-800 • C) and weight space velocities (WSV = 70,000-350,000 Nml g cat −1 h −1 ). Coating load was controlled by multiple depositions; homogeneous and well adherent layers were found. Catalytic tests demonstrated superior performances of the bimetallic samples (Ni-Rh/CeO 2 ) compared to the monometallic one (Ni/CeO 2 ), especially at high space velocity. At the same time, foam showed better performances with respect to the monolithic support toward the SR and OSR processes.
