Use of moo3 catalyst on the cathode to reduction of oxygen gas

The aim of this study is to produce a porous cathode has high catalytic efficiency for lithium air battery. Catalyst of the cathode was prepared addition of MoO3, which activate different duration at 500°C of a muffle furnace in gel occurs glycine, glycerol and carbon. Gel mixture was applied over the stainless steel base was used electrochemical measurements as the working electrode. The catalytic efficiencies of prepared electrodes for oxygen reduction process were determined at oxygen atmosphere in lithium perchlorate (10%), ethylene carbonate (45%), dimethyl carbonate (45%) solution by using cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and cathodic polarization techniques. Surface images of prepared electrodes were examined with scanning electron microscope (SEM). The effective catalyst for oxygen reduction inside of prepared gel includes the catalyst has different duration time is MoO3 catalyst at 8 h 500 °C.
