Title:
デンドライト的構造を有するマンガン酸化物ナノ構造体の製造方法及びデンドライト的構造を有する遷移金属酸化物ナノ構造体を含む酸素還元電極
Document Type and Number:
Japanese Patent JP3873197
Kind Code:
B2
Abstract:
An object of the present invention is to provide an oxygen reduction electrode having excellent oxygen reduction properties (oxygen reduction catalyst abilities). The present invention encompasses: (1) A method for manufacturing a nanostructured manganese oxide having a dendritic structure formed from an agglomeration of primary particles, wherein the method comprises the steps of: removing components from a target plate that comprises one or more kinds of manganese oxides by irradiating the target plate with laser light in an atmosphere comprising a mixed gas of inert gas and oxygen gas, the content of the oxygen gas in the mixed gas being no less than 0.05% but no more than 0.5% as measured by mass flow rate; and depositing the removed components on a substrate that is opposed to the target plate substantially in parallel to obtain the nanostructured manganese oxide, and (2) an oxygen reduction electrode comprising a nanostructured transition metal oxide having a dendritic structure formed from an agglomeration of primary particles.
