METHOD FOR PRODUCING MANGANESE OXIDE NANOSTRUCTURE AND OXYGEN REDUCTION ELECTRODE USING SUCH MANGANESE OXIDE NANOSTRUCTURE

摘要

Disclosed is an oxygen reduction electrode with excellent catalytic power for oxygen reduction. Also disclosed is a method for producing a manganese oxide nanostructure which is composed of secondary particles as agglomerates of primary particles of manganese oxide and has catalytic power for oxygen reduction. The method comprises a step wherein a target plate of manganese oxide is irradiated with laser light for separating the constituting material from the target plate and depositing the thus-separated material on a substrate which is arranged substantially parallel to the target plate.
