Abstract
The double perovskite oxides LaSrFeMo 0.9 Co 0.1 O 6 was prepared by co-precipitation method and sol-gel method. The title catalysts were calcined at 800 ° C and characterized by XRD H 2 -TPR, SEM and TG-DTA techniques. The catalytic activity was evaluated for methane combustion. The specific surface area of them was calculated by BET model. The samples exhibit significant catalytic activity for methane combustion at 800 ° C. Upon calcination at 800 ° C, the LaSrFeMo 0.9 Co 0.1 O 6 prepared by sol-gel method retains a specific surface area of 24 m 2. g -1 and shows an excellent activity for methane combustion (the conversion of 10% and 90% are obtained at 505 ° C and 660 ° C, respectively).
