Abstract

Provided is an oxygen reduction catalyst having a high oxygen reduction performance. An oxygen reduction catalyst according to the present embodiment includes a transition metal oxide to which an oxygen defect is introduced, and a layer that is provided on the transition metal oxide and that contains an electron conductive substance. A method for producing an oxygen reduction catalyst according to the present embodiment includes heating a transition metal carbonitride as a starting material in an oxygen-containing mixed gas. In addition, a method for producing an oxygen reduction catalyst according to the present embodiment includes heating a transition-metal phthalocyanine and a carbon fiber powder as starting materials in an oxygen-containing mixed gas.
