The perovskite-type ferrites (Gd,Sr)(n+1)FenO3n+1 (n=1, 2, infinity) were studied. Obtained catalytic properties in carbon dioxide methane reforming. It is shown that an increase in the number of perovskite layers (n) in the complex oxides structure leads to an increase in the catalytic activity. It was established that the increase of content Fe4+ in complex oxides leads to a decrease in the catalytic activity of ferrites
