Method for producing electrode for oxygen reduction, electrode for oxygen reduction and electrochemical device using the same

摘要

The main object of the present invention is to provide an electrode for oxygen reduction that gives a four-electron reduction reaction with higher selectivity in the reaction of reducing oxygen. The present invention is a method for producing an oxygen reduction electrode used for 4-electron reduction of oxygen, wherein (1) a first step of obtaining a carbide by carbonizing a starting material containing a nitrogen-containing synthetic polymer and ( 2) It relates to a production method having a second step of producing the oxygen reduction electrode using an electrode material containing the carbide.
