LaMn 1−y Co y O 3 (y=0–0.5) catalysts were synthesized by sol–gel methods and characterized by BET and XRD. The catalytic activities were non-linear enhanced by cobalt substitution, and achieved the highest level (76.5%) on LaMn 0.9 Co 0.1 O 3 . The reducibility was investigated by the oxygen storage capacity and H 2 -TPR measurements. The stability...
