Effects of excess manganese in lanthanum manganite perovskite on lowering oxidation light-off temperature for automotive exhaust gas pollutants

The effects of excess manganese on enhancement of oxidation activity of LaMn 1+ x O 3+ δ perovskite for CO and propane removal from a synthetic automotive exhaust gas are reported. Various LaMn 1+ x O 3+ δ ( x = 0.05–0.4) perovskite-type nanocatalysts were prepared by a microwave-assisted “gel combu...
