Embodiment Construction
[0036] 1. Cleaning of conductive glass: Use distilled water, absolute ethanol, and acetone to ultrasonically clean the cut conductive glass for 30 minutes in sequence, and dry it for later use.
[0037] 2. Platinum grid electrode: drip chloroplatinic acid solution with a syringe at 5 μl / s on the side of the cleaned FTO (100mm×120mm) conductive glass, put it in a muffle furnace and heat it at 400°C for 30min, take it out for use Anhydrous ethanol clear.
[0038] 3. TiO 2 Preparation of slurry: The slurry was mixed with P25, absolute ethanol, OP emulsifier, acetylacetone, and PEG2000 in a ratio of 20:1:1:4, stirred on a magnetic stirrer for 1 hour, and left to stand for 10 minutes for later use.
[0039] 4. Electrostatic spraying TiO 2 Thin film: TiO 2 The slurry is sucked into a 10ml syringe and installed on the syringe pump. Set the flow rate to 0.5ml / min. Turn on the CCD industrial camera and adjust the high-voltage DC stabilized current power supply. When the jet mode ch...
