It was found that SrFeO3-xhas the oxygen breathing properties.The oxygen adsorption isotherms of SrFeO3-x were measured at temperature ranging from 300℃ to 700℃.The oxygen saturated adsorptivity increased with reducing temperature.And the activity of SrFeO3-x catalysing the oxidation of toluene was measured in air.Experimental results showed that the conversation of toluene on SrFeO3-x in air was improved with temperature rising up and space velocity slowing down.
