摘要： Disclosed is a method for preparing hematite iron oxide having various nanostructures, including: preparing a mixture solution by adding iron chloride and caffeine to a solvent and magnetically stirring; and performing hydrothermal synthesis, wherein the solvent is selected from water, ethanol, propanol and methanol. In accordance with the present disclosure, hematite iron oxide (α-Fe2O3) superstructures of various shapes, including grape, cube, dumbbell and microsphere shapes, can be synthesized in different solvents using caffeine. The shapes can be controlled variously via a simple one-step synthesis route without using a growth-inducing agent and without separation based on size. The prepared hematite iron oxide exhibits high coercivity at room temperature owing to its fine crystal structures and anisotropic shapes. The hematite iron oxide nanoparticles having different nanostructures prepared according to the present disclosure may be widely useful in biological and biochemical applications as a material having peroxidase mimic activity and thus capable of replacing natural enzymes.
