Abstract

The steam reforming of ethanol was performed over Co and Ni catalysts supported on perovskite-type oxides (LaAlO₃, SrTiO₃ and BaTiO₃). Co and Ni catalysts supported on LaAlO₃ and SrTiO₃ showed high catalytic activities and long-term stabilities and suppressed coke formation while Co/BaTiO₃ showed lower catalytic activities and poorer coking resistance. The average particle size of Co on BaTiO₃ was larger than that on SrTiO₃. Lattice oxygen in perovskites may play positive roles in hindering coking and Co/SrTiO₃ has more frequent participation of lattice oxygen in the oxidation of intermediates or precursor of coke in comparison with Co/BaTiO₃.
