Examples
Embodiment 1
[0022] 0.16gFeCl 3 ·6H 2 O was dissolved in a mixed solution of 2 mL of water and 18 mL of ethanol, 0.1 g of glycine was added, and then the above mixture was transferred to a hydrothermal kettle and heated at 160 °C for 12 h. After naturally cooling to room temperature, the red powder collected by centrifugation is the product, and the obtained product is multilayer α-Fe 2 o 3 Hollow nanostructures.
Embodiment 2
[0024] 0.16gFe(NO 3 ) 3 ·6H 2 O was dissolved in a mixed solution of 2 mL of water and 18 mL of ethanol, 0.1 g of glycine was added, and then the above mixture was transferred to a hydrothermal kettle and heated at 160 °C for 12 h. After naturally cooling to room temperature, the red powder collected by centrifugation is the product, and the obtained product is multilayer α-Fe 2 o 3 Hollow nanostructures.
Embodiment 3
[0026] 0.16gFeCl 3 ·6H 2 O was dissolved in a mixed solution of 10 mL of water and 10 mL of ethanol, 0.1 g of glycine was added, and then the above mixture was transferred to a hydrothermal kettle and heated at 160 °C for 12 h. After naturally cooling to room temperature, the red powder collected by centrifugation is the product, and the obtained product is multilayer α-Fe 2 o 3 Hollow nanostructures.
