[0016] A preparation method of mesoporous hollow iron oxide microspheres, comprising the following steps:
[0017] S1. Glucose is dissolved in pure water, then placed in a polytetrafluoroethylene hydrothermal reaction kettle, and reacted at 160-220°C for 4-12 hours to obtain substance A for later use;
[0018] Preferably, in step S1, the volume ratio of glucose to pure water is 0.7-1:10;
[0019] S2. Dissolve iron acetylacetonate in triethylene glycol and stir evenly to obtain solution B, then mix substance A and solution B at a volume ratio of 1 to 1.5:50, stir evenly and put it into a hydrothermal reaction kettle Inside, react at 160-220°C for 8-24 hours, cool and wash to obtain substance C, and set aside;
[0020] Preferably, in step S2, the volume ratio of iron acetylacetonate to triethylene glycol is 1-2:250;
[0021] Preferably, in step S2, washing with ethanol;
[0022] S3. Put the substance C into a muffler furnace and calcinate at 250-350° C. for 4-12 hours to obta...
Embodiment 1
[0029] S1. Weigh 5g of glucose, put it into 50mL of pure water, stir until the glucose is completely dissolved, transfer it to a polytetrafluoroethylene hydrothermal reaction kettle, react at 160°C for 12, wash and dry after cooling to prepare substance A for later use.
[0030] S2. Dissolve 0.2g of iron acetylacetonate in 50mL of triethylene glycol, stir evenly (stir for 5min to be uniform), and prepare solution B, then take 1g of substance A and add it to 50g of solution B, stir evenly and put it into a hydrothermal In the reaction kettle, react at 200°C for 22 hours, wash and dry with ethanol after cooling, and obtain substance C for later use;
[0031] S3. Put the substance C into a muffler furnace and calcinate at 250° C. for 12 hours to obtain mesoporous hollow iron oxide microspheres.
Embodiment 2
[0033] S1. Weigh 3.5g of glucose, put it into 50mL of pure water, stir until the glucose is completely dissolved, transfer it to a polytetrafluoroethylene hydrothermal reaction kettle, react at 200°C for 8h, wash and dry after cooling to prepare substance A for later use.
[0034] S2. Dissolve 0.4g of iron acetylacetonate in 50mL of triethylene glycol, stir evenly (stirring for 5 minutes to be uniform), and prepare solution B, then take 1.5g of substance A and add it to 50g of solution B, stir well and put it into water In the thermal reaction kettle, react at 180°C for 10 hours, wash and dry with ethanol after cooling, and obtain substance C for later use;
[0035] S3. Put the substance C into a muffler furnace and calcinate at 300° C. for 8 hours to obtain mesoporous hollow iron oxide microspheres.
