Embodiment 1
[0036] (1) TiO 2 Preparation of nanotube carrier: Sol-gel method and high-pressure hydrothermal reaction were adopted. Dissolve the calculated amount of butyl titanate in a certain amount of absolute ethanol, add dropwise a mixture of absolute ethanol, glacial acetic acid and deionized water under stirring, and continue stirring after hydrolysis to form a sol, and let it stand for 2- After 3 days, the powder obtained after vacuum drying at 80°C for 8-10 hours is ground and then calcined in air at 500°C for 3 hours in a muffle furnace to obtain nano-TiO 2 powder. TiO will be produced 2 Add the powder into the liner of the autoclave, add 10mol / L NaOH solution and mix, and react at 150°C for 24 hours. The obtained samples were washed with deionized water and 0.1mol / L HCl solution respectively, dried at 80°C, and air roasted in a muffle furnace at 500°C for 3 hours to obtain TiO 2 nanotube. The consumption molar ratio of butyl titanate, dehydrated alcohol, glacial acetic acid...
