Embodiment 1
[0020] Put 112mL of analytically pure titanium tetrachloride solution into a three-neck flask, add 388mL of distilled water dropwise in an ice bath, and the temperature does not exceed 20°C. A stock solution of titanium dioxide (solution I) with a concentration of about 2 mol / L was obtained. Get solution I 20mL, weigh 0.0652 grams of ytterbium oxide, 0.0652 grams of erbium oxide, after stirring and dissolving, add 100ml distilled water. It was hydrolyzed at 50°C for 4 hours to obtain a transparent solution. Toluene and trioctylamine (volume ratio: 2:1) were used as the extractant to shake and extract the above hydrolyzed transparent solution for 15 minutes at room temperature. The aqueous phase and the organic phase were separated, and the organic phase was back-extracted with 10% NaOH 20mL at room temperature, and the obtained organic phase could be used repeatedly. Until the pH value of the aqueous phase is 6.5-7. Aging for 24 hours to obtain a transparent anatase-type na...
Embodiment 2
[0023] Take 20 mL of solution I in Example 1, weigh 0.0652 g of ytterbium oxide and 0.0652 g of holmium oxide, stir and dissolve, and then add 80 ml of distilled water. It was hydrolyzed at constant temperature at 60°C for 3 hours to obtain a transparent solution. Toluene and trioctylamine (volume ratio: 2:1) were used as the extractant to shake and extract the above hydrolyzed transparent solution for 15 minutes at room temperature. The aqueous phase and the organic phase were separated, and the organic phase was back-extracted with 10% NaOH 20mL at room temperature, and the obtained organic phase could be used repeatedly. Until the pH value of the aqueous phase is 6.5-7. Aging for 24 hours to obtain a transparent anatase-type nano-titanium dioxide gel, take about 50 grams of the titanium dioxide gel, add it to a hydrothermal reaction kettle, add distilled water to 70% of the reaction kettle, and conduct a hydrothermal reaction at 200°C After 6 hours, cool to room temperatu...
Embodiment 3
[0026]Take 20 mL of solution I in Example 1, weigh 0.0652 g of ytterbium oxide and 0.0652 g of thulium oxide, stir and dissolve, then add 80 ml of distilled water. It was hydrolyzed at 50°C for 4 hours to obtain a transparent solution. Toluene and trioctylamine (volume ratio: 2:1) were used as the extractant to shake and extract the above hydrolyzed transparent solution for 15 minutes at room temperature. The aqueous phase and the organic phase were separated, and the organic phase was back-extracted with 10% NaOH 20mL at room temperature, and the obtained organic phase could be used repeatedly. Until the pH value of the aqueous phase is 6.5-7. After aging for 24 hours, a transparent anatase-type nano-titanium dioxide gel was obtained. Take about 50 grams of the titanium dioxide gel, add it to a hydrothermal reaction kettle, add distilled water to 70% of the reaction kettle, and conduct a hydrothermal reaction After 3 hours, cool to room temperature, open the kettle, separat...
