[0017] First, at a mass ratio of 1:10, tetrabutyl titanate and a mass fraction of 5% acetic acid solution were stirred and mixed for 10 minutes, then after standing for 6 hours, and after ultrasonic dispersion at 200W for 10 minutes, the dispersion liquid was collected, and the mass ratio was 1:8. , add 70% nitric acid and nitric acid to the dispersion, and heat it in a water bath at 75 °C for 1 h; after the heating in the water bath is completed, collect the mixture, and then mix the mixture with deionized water at a mass ratio of 1:10. , then heated in an oil bath at 200 °C for 10 h, then left to cool to room temperature, rotary evaporated to 1 / 5 of the original volume at 75 °C, collected the concentrate and centrifuged at 2500 r / min for 10 min, and removed the supernatant. And at a mass ratio of 1:10, the remaining mixture was stirred and mixed with a mass fraction of 50% ethanol solution to prepare a mixed slurry; the mixed slurry prepared above was evenly coated on the sur...
