CATALYTIC MATERIALS AND ELECTRODES FOR OXYGEN EVOLUTION, AND SYSTEMS FOR ELECTROCHEMICAL REACTION

摘要

The present invention relates to an oxygen generation catalyst, which exhibits an improved catalytic characteristic even under a neutral condition, and also relates to an electrode including the oxygen generation catalyst, and an electrochemical reaction system. An oxygen generation catalyst according to an embodiment of the present invention comprises trivalent manganese, and non-stoichiometric manganese oxide represented by chemical formula 1: Mn_(1-)O, where satisfies 0 0.5.
