NOVELTY - An alpha -iron(III) oxide (Fe2O3) mesoporous nanorod/nitrogen-doped graphene composite material is prepared by adding pore-forming agent in deionized water to obtain organic solution, adding alkali source and aqueous solution of inorganic iron to the organic solution to form transparent mixed liquid, and adding graphene oxide to the transparent mixed liquid to obtain stable suspension; and pouring suspension into a hydrothermal reaction kettle and reacting at 100-200 degrees C for 5-36 hours to obtain the composite material. USE - Method of preparing alpha -iron(III) oxide (Fe2O3) mesoporous nanorod/nitrogen-doped graphene composite material (claimed) used in sulfamethoxazole degradation. ADVANTAGE - The method utilizes simple device, has mild reaction condition and low cost of reagent, and is safe and suitable for large scale production. DETAILED DESCRIPTION - Preparation of alpha -Fe2O3 mesoporous nanorod/nitrogen-doped graphene composite material comprises: (A) adding pore-forming agent in deionized water, mixing and stirring for 3-10 minutes to obtain organic solution, adding alkali source and aqueous solution of inorganic iron to the organic solution, stirring for 5-10 minutes to form transparent mixed liquid; (B) adding graphene oxide to the transparent mixed liquid, ultrasonically treating for 0.3-2 hours, then stirring for 2-4 hours to obtain stable suspension; and (C) pouring suspension into a hydrothermal reaction kettle and reacting at 100-200 degrees C for 5-36 hours, naturally cooling to room temperature, then using deionized water to wash 3 times, then using alcohol to wash twice, and drying at 50 degrees C for 12 hours to obtain the composite material.
