New mechanisms of oxygen reduction on perovskite related oxides LaLi0:1M0:1Fe0:8O3−d (M = Fe, Co, Ni) and a rock salt type oxide Li0:1Ni0:9O have been proposed. Based on these mechanisms, a comparison of catalytic activity of the oxides in the temperature range 820–1000 K has been done. It has been shown that catalytic activity of LaLi0:Co0:1Fe0:8O3−d oxide exceeds the activity of Li0:1Ni0:9O below 970 K.
