SrCo0.8Fe0.2O3-δ (SCF) nanopowders have been successfully synthesized by rapid microwave-assisted sol-gel combustion(MWSG) method. For comparison, SCF were also synthesized by conventional heating synthesis method: liquid citrate sol-gelcombustion (LC) method and EDTA sol-gel combustion (EDTA) method. All obtained samples were characterized by X-raydiffraction (XRD), environmental scanning electron microscopy (ESEM) analyses and specific surface area (BET) analyses. The results shows that SCF182 prepared by MWSG method showed the greatest oxygen production properties with smallestparticle size and largest surface are compared to those synthesized by LC and EDTA methods. Moreover, the SCF synthesizedvia MWSG method showed excellent cyclic performance after cycles. Thus, MWSG is a novel, time saving, energy-efficientand promising method to synthesize SCF perovskites. The MWSG reported in this paper is expected to be extended to thepreparation of other perovskite nano-powders.
