▎ 摘　　要

NOVELTY - The composition has a combination of transition metal phthalocyanines in the range of 5% to 45%, 50% graphene oxide and/or reduced graphene oxide and an additive, where sizes of the metal phthalocyanines aggregates comprise a range of 10 nanometer to 5 micrometer and the graphene oxide and or reduced graphene oxide include a sheet form of thickness in the range of 0.8 to 1.2 nanometer and a length of up to 3 picometer. A system in a rotary electrode amperometry configuration in a disk/ring configuration is an electrode comprising nanocomposite that reaches a specified current density. USE - Electroactive nanocomposite composition for preparing paint for coating of electrodes. ADVANTAGE - The method enables preparing the paint at low with simplified synthetic processing and enhancement of catalytic activity and stability for oxygen reduction reaction (ORR). DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an atomic force microscopy image of graphene oxide flake.(Drawing includes non-English language text).
