▎ 摘　　要

NOVELTY - Synthesis of magnetic nano-hybrid based on graphene, ferrite and water involves (i) forming a hybrid graphene material with magnetic properties using metallic ion, graphite, and water as precursor with high natural organic substance content. USE - Synthesis of magnetic nano-hybrid based on graphene, ferrite and water used as adsorbent, catalyst, anti-fungal and/or bactericidal agent and for forming composite, biomaterial, electrode, sensor, battery, capacitor and fuel cell, and used for telecommunication, chemical, electrical, electronic, automobile, oil, petrochemical, desalination, textile, civil construction, aerospace and health science applications (all claimed). ADVANTAGE - The method simply and economically provides environmentally-friendly magnetic nano-hybrid having high content of natural organic substance, and high quality graphene hybrid sheet.
