摘要：

Nanometer oxides La1-xSrxMnO3 were synthesized by absolute alcohol as solvent.The desired metal cations were chelated in a solution using citric acid as the chelating agents.In order to get the optimum preparation condition for La1-xSrxMnO3,the pH of primal commix solution,the molar fraction of citric acid and baking temperature of predecessor block were researched by orthogonal test design method with different x.The thermal decomposition of the metal carboxylate precursor gels was studied by TG/DTA and the products derived from calcinations of the gels were characterized by XRD and TEM.The polarization curves were acquired on an electrochemical work station(LK98)and the discharge curves were acquired on a testing instrument of batteries(DC-5)with a constant current discharge under 120 mA/cm2.The results reveal that the nanometer oxides can be achieved by absolute alcohol as solvent and it has better catalytic activity.
