Embodiment 1
[0055] Take a rectangular pure titanium foil with a thickness of 0.1 mm as a sample, which is 15 mm long and 10 mm wide. The surface of the sample was sequentially polished with 400-1500 grit sandpaper, and then ultrasonically cleaned in acetone, absolute ethanol and deionized water for 10 minutes.
[0056] Measure 1 mL of hydrofluoric acid into 100 mL of deionized water to make a hydrofluoric acid solution. At room temperature, with the cleaned titanium foil substrate as the anode and the platinum sheet as the cathode, anodize at 30V for 30min in the above mixed solution. Then the sample was placed in a muffle furnace and calcined at 450 °C for 2 hours, and then cooled to room temperature with the furnace, that is, TiO was prepared on the surface of the titanium foil substrate. 2 nanotube array film.
[0057] Using cyclic voltammetry deposition method, first on TiO 2 Graphene quantum dots are deposited on the surface of the nanotube array film. 0.1 g of graphite oxide was...
