Embodiment 1
[0038] a. Preparation of doped SiO 2 TiO 2 Slurry:
[0039] Take 5g of P25 powder, SiO 2 with TiO 2 Mix well, SiO 2 The mass of TiO 2 2.5% of the mass, add 1mL acetic acid in turn, add 5ml deionized water in 5 times at 1mL each time, add 15mL absolute ethanol in 15 times at 1mL each time, add 15mL in 6 times at 2.5mL each time For absolute ethanol, stir for 3 minutes each time liquid is added; then add 100 mL of absolute ethanol to obtain a slurry; stir the slurry magnetically for 10 minutes at a stirring speed of 300 rpm; then disperse by ultrasonic for 60 minutes; then add 20 g Terpineol, repeated magnetic stirring and ultrasonic dispersion; then added 3g of ethyl cellulose and 30g of absolute ethanol to repeat magnetic stirring and ultrasonic dispersion; finally in a rotary evaporator at 40 ° C for 6 hours to obtain the available for screen printing Slurry, denoted as slurry B.
[0040] b. Preparation of doped SiO 2 TiO 2 The nanocrystalline porous composite film: ...
Embodiment 2
[0046] The preparation method of the present embodiment is the same as embodiment 1, and the difference is that SiO 2 The amount of addition is TiO 2 5% of the mass, the slurry that can be used for screen printing obtained in step a is denoted as slurry C.
Embodiment 3
[0048] The preparation method of the present embodiment is the same as embodiment 1, and the difference is that SiO 2 The amount of addition is TiO 2 7.5% of the mass, the slurry that can be used for screen printing obtained in step a is denoted as slurry D.
[0049] The printed four-layer SiO 2 / TiO 2 The paste has a film thickness of about 17.9 μm after sintering. Depend on Figure 4 , 5. It can be seen that the composite film is smooth, the nanoparticles are evenly distributed, and form a network structure connected to each other. In the case of relatively large particles (TiO 2 ) around the distribution is relatively small (for SiO 2 ) particles, the small particles not only increase the TiO 2 efficient connection between the particles, and also enables the TiO 2 The bond with conductive glass is stronger.
