The low amount of coke formation in spite of the activity decrease observed over both imp-Ni/TiO2 and spc-Ni/TiO2 may be due to the presence of mobile oxygen over TiO2 as seen in the strong metal-support interaction (SMSI). Ni-supported catalysts on perovskite-type oxides have been prepared by ``solid phase crystallization'' (spc) method [ Last edited by Âõ²½´ÓÍ·Ô½ on 2009-9-5 at 19:00 ] |
