▎ 摘　　要

NOVELTY - The method involves utilizing phosphorus-containing poly-ionic liquid nitrogen as a precursor. A certain amount of graphene oxide is added. Functional groups with ionic liquid are mixed with an oxidized graphite alkene group at high temperature for forming a structure of a carbon material with high catalytic activity. Mixing process of ionic liquid and oxidized graphite alkene is performed by utilizing water as solvent without using toxic or high cost reagent. USE - Graphene oxide/ionic liquid composite nano-catalytic material manufacturing method. ADVANTAGE - The method enables realizing larger active area and high oxygen reduction catalytic activity, and ensuring simple process. DESCRIPTION OF DRAWING(S) - The drawing shows a graph illustrating relation between current density and potential.
