摘要
Abstract
Perovskite type oxides LaNio.8Co0.2O3 were prepared via sol-gel method by using acetone and glycol as solvent, then the air electrode was prepared. The structure of the catalyst was analyzed by XRD and TEM. Polarization curves,chronoamporometry, AC impedance method. The galvanostatic discharge curves were used to test the porformance of the catalyst in 7 mol/L KOH solution. The catalyst prepared by complex organic solvent had the better electrochemical porformance. The oxygen reduction current density was 273 mA/cm2 at the electrode potential of -0.4 V (vs. Hg/HgO).关键词
