Examples
Embodiment 1
[0040] 0.75 g KMnO 4 and 1.30 g K 2 S 2 o 8 Dissolve in 15 mL deionized water. The above-mentioned mixed solution was placed in a reactor for hydrothermal high-temperature reaction, the temperature was 140°C, and the reaction time was 24 hours. After the reaction, the product was washed with deionized water and alcohol, and dried in a vacuum oven at 60°C to obtain MnO 2 Nanowires, the nanowires have a diameter of about 20-25nm and a length of about 1 μm.
[0041] 0.1 gram of MnO prepared by the above reaction 2 Nanowires with 2 grams of gelatin, 2 grams of SiO 2 Nanoparticles (approximately 50 nm in diameter) were mixed and dispersed in 50 ml of deionized water and sonicated for 30 min. After that, the above mixed solution was placed in an oven at 80°C until the solvent was completely evaporated, and further freeze-dried at -40°C for 12 hours. The obtained product was subjected to heat treatment, and the heat treatment conditions were first treated at 300°C for 2 hours...
