Embodiment 1

[0027] Weighing 1.6G FECL 3 · 6h2 O and dissolved in 60 mL of deionized water, the formulated solution was transferred to a high pressure hydrothermal reactor having a volume of 100 mL. Then, the reaction kettle was placed in an oven at a temperature of 100 ° C for 4 h, naturally cooled to room temperature. The yellow precipitate obtained by the experiment was subsequently washed 3 times with ionized water and alcohol, centrifuged and dried at 60 ° C to give a yellow powder β-FeoOH, which was named FeooH-4H. Subsequently, 20 mg of beta-FeOOH powder was weighed, and they were placed in 6 ml of tripermine, and the ultrasonic cleaning washable was easily dispersed in three octamines. 200 μl of oleic acid was added to the suspension obtained after dispersion, stirred for 1 h, and then transferred to the centrifuge, and centrifuge at 7500 rpm for 5 min to obtain a glue mixture. Transfer the above mixture to a sealed high temperature tube furnace, and AR / H is introduced into the cooke...

[0030] Weighing 1.6G FECL 3 · 6h 2 O and dissolved in 60 mL of deionized water, the formulated solution was transferred to a high pressure hydrothermal reactor having a volume of 100 mL. The reactor was then placed in an oven at a temperature of 100 ° C for 10 h, naturally cooled to room temperature. The yellow precipitate obtained by the experiment was subsequently washed 3 times with ion and alcohol, centrifuged and dried under 80 ° C to give a yellow powder β-feoOH, which was named FeOH-10H. Subsequently, 20 mg of β-FeOOH powder was weighed, and they were placed in 6 mL of triperlamine, and the ultrasonic cleaning washable was easily dispersed in three octamines. 200 μl of oleic acid was added to the suspension obtained after dispersion, stirred for 2 h, and then transferred to the centrifuge, centrifugation at 7500 rpm to obtain a glue mixture. Transfer the above mixture to a sealed high temperature tube furnace, and AR / H is introduced into the cooker. 2 Mixed atmosphere (wh...

Embodiment 3

[0033] Weighing 1.6G FECL 3 · 6h 2 O and dissolved in 60 mL of deionized water, the formulated solution was transferred to a high pressure hydrothermal reactor having a volume of 100 mL. The reactor was then placed in an oven at a temperature of 100 ° C for 6 h, and naturally cooled to room temperature. The yellow precipitate obtained by the experiment was then cleaned with ionized water and alcohol, centrifugally, and dried under 60 ° C to give a yellow powder β-feoOH, which was named FeOH-6H. Subsequently, 20 mg of β-FeOOH powder was weighed, and they were placed in 6 mL of triectine, and the ultrasonic cleaning washable was solened to uniformly dispersed in three octamines. 200 μl of oleic acid was added to the suspension obtained after dispersion, stirred for 1 h, and then transferred to a centrifuge, and centrifuged at 8500 rpm to obtain a glue mixture. Transfer the above mixture to a sealed high temperature tube furnace, and AR / H is introduced into the cooker. 2 Mixed atmo...
