NOVELTY - Preparing magnetic graphene catalyst comprises (i) using sol-gel method in preparing SrCo0.8Fe0.2O3 delta -powder, (i) taking SrCo0.8Fe0.2O3powder in the tubular furnace, and introducing protective gas, heating at 500-550 degrees C, (iii) changing the gas, introducing protective gas and hydrogen, reducing SrCo0.8Fe0.2O3 delta -powder, (iv) changing the gas, introducing protective gas, heating at 700-750 degrees C, changing the gas, introducing protective gas, hydrogen gas and carbon source, reacting at constant temperature, changing the gas, introducing protective gas, cooling to obtain the product. USE - The magnetic graphene catalyst is useful in industrial catalysis for catalyze oxidation of cyclohexane (claimed). ADVANTAGE - The catalyst has good magnetic property and can be recovered easily.
