▎ 摘　　要

NOVELTY - The material has composite material part coated with base material by utilizing nitrogen-doped graphene and ferrite. Mass ratio of the nitrogen-doped graphene and ferrite is about 1:1-1:10. The base material is contained with rare pneumatic doped graphite. Doped amount of the rare pneumatic doped graphite is about 2%. USE - Nitrogen-doped graphene/ferrite nanometer composite material. ADVANTAGE - The material avoids reduction adulterated doping phenomenon of nitrogen atom so as to change graphene surface chemical property on a graphene surface for realizing chemical graphene preparation process in a defect surface, thus performing alkaline urea hydrolysis operation. The material ensures that a nitrogen-doped graphite alkene surface is adhered with ferrite so as to realize ferrite nanometer particle agglomeration accumulation operation, thus preventing a graphene layer from damaging and improving electro-chemical property of the composite material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a nitrogen-doped graphene/ferrite nanometer composite material preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a graph illustrating relationship between nitrogen-doped graphene/ferrite nanometer composite material preparation characteristics.
