Example Embodiment
[0028] Example 1: First, mix an aqueous solution containing 0.1M ferric chloride and 0.15M urea with ethanol (alcohol / water volume ratio = 5:1) and then put it into a three-necked flask; heat under reflux for 8 hours under continuous stirring; The product was separated by suction filtration, and the product was washed with ethanol and distilled water 3 times and dried in an oven at 60°C to obtain iron oxyhydroxide nanorods; the iron oxyhydroxide nanorods accounting for 0.05% by weight of the ethanol / water mixed system were dispersed Stir evenly in the ethanol / water mixed system with a volume ratio of 20:1, then put it into a stainless steel reactor with a filling degree of 80%; treat it at 160℃ for 8 hours, cool naturally, and wash the product with ethanol and distilled water for 3 times and then put it in the oven Hollow iron oxide balls can be obtained after medium drying.
Example Embodiment
[0029] Example 2: First, mix an aqueous solution containing 0.3M ferric chloride and 0.45M urea with n-propanol (alcohol / water volume ratio = 1:1) and put it into a three-necked flask; heat to reflux for 4 hours under continuous stirring; The obtained product was separated by suction filtration, and the product was washed with ethanol and distilled water 3 times, and then dried in an oven at 60°C to obtain iron oxyhydroxide nanorods; the iron oxyhydroxide nanorods accounted for 0.05% by weight of the ethanol / water mixed system Disperse in the ethanol / water mixed system with a volume ratio of 30:1, stir well, and then put it into a stainless steel reactor with a filling degree of 70%; treat it at 180°C for 10 hours, cool naturally, and wash the product with ethanol and distilled water 3 times each. After drying in an oven, hollow iron oxide balls can be obtained.
Example Embodiment
[0030] Example 3: First, mix an aqueous solution containing 0.3M ferric chloride and 0.45M urea with isopropanol (alcohol / water volume ratio = 1:5) and put it into a three-necked flask; heat to reflux for 4 hours under continuous stirring The obtained product was separated by suction filtration, the product was washed with ethanol and distilled water for 3 times, and then dried in an oven at 60 ℃ to obtain iron oxide hydroxide nanorods; the weight ratio of 4.0% of the ethanol / water mixed system was iron oxide hydroxide nanorods The rods are dispersed in an ethanol / water mixed system with a volume ratio of 10:1 and stirred evenly and then put into a stainless steel reactor with a filling degree of 80%; treated at 200°C for 4 hours, naturally cooled, and the product is washed 3 times with ethanol and distilled water each After drying in an oven, hollow iron oxide balls can be obtained.
