Abstract

Activity tests and some characterizations were conducted on Co supported catalyst during and after toluene steam reforming. FE-TEM measurements and XPS measurements revealed that an anchoring behavior between Co metals and a support oxygen was confirmed only when La ion and lattice defection coexist in/on the support oxygen. Also, a redox property of support is significant for activating steam and toluene according to SSITKA (Steady State Isotopic Transient Kinetic Analysis) and XPS measurements. Compatibility of the anchoring behavior and the redox property enabled 10wt%Co/La_0.7Sr_0.3AlO_2.85 to indicate highest activity during toluene steam reforming.
